Functionalized 3-(5-ar-yloxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(4-substituted-phen-yl)prop-2-en-1-ones: synthetic pathway, and the structures of six examples.

Five examples each of 3-(5-ar-yloxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-[4-(prop-2-yn-1-yl-oxy)phen-yl]prop-2-en-1-ones and the corresponding 1-(4-azido-phen-yl)-3-(5-ar-yloxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)prop-2-en-1-ones have been synthesized in a highly efficient manner, starting from a common source precursor, and structures have been determined for three examples of each type. In each of 3-[5-(2-chloro-phen-oxy)-3-methyl-1-phenyl-1H-pyrazol-4-yl]-1-[4-(prop-2-yn-1-yl-oxy)phen-yl]prop-2-en-1-one, C28H21ClN2O3, (Ib), the isomeric 3-[5-(2-chloro-phen-oxy)-3-methyl-1-phenyl-1H-pyrazol-4-yl]-1-[4-(prop-2-yn-1-yl-oxy)phen-yl]prop-2-en-1-one, (Ic), and 3-[3-methyl-5-(naphthalen-2-yl-oxy)-1-phenyl-1H-pyrazol-4-yl]-1-[4-(prop-2-yn-yloxy)phen-yl]prop-2-en-1-one, C32H24N2O3, (Ie), the mol-ecules are linked into chains of rings, formed by two independent C-H⋯O hydrogen bonds in (Ib) and by a combination of C-H⋯O and C-H⋯π(arene) hydrogen bonds in each of (Ic) and (Ie). There are no direction-specific inter-molecular inter-actions in the structure of 1-(4-azido-phen-yl)-3-[3-methyl-5-(2-methyl-phen-oxy)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one, C26H21N5O2, (IIa). In 1-(4-azido-phen-yl)-3-[5-(2,4-di-chloro-phen-oxy)-3-methyl-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one, C25H17Cl2N5O2, (IId), the di-chloro-phenyl group is disordered over two sets of atomic sites having occupancies 0.55 (4) and 0.45 (4), and the mol-ecules are linked by a single C-H⋯O hydrogen bond to form cyclic, centrosymmetric R 2 2(20) dimers. Similar dimers are formed in 1-(4-azido-phen-yl)-3-[3-methyl-5-(naphthalen-2-yl-oxy)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one, C29H21N5O2, (IIe), but here the dimers are linked into a chain of rings by two independent C-H..π(arene) hydrogen bonds. Comparisons are made between the mol-ecular conformations within both series of compounds. © Kiran Kumar et al. 2020.

Chemical context

Chalcones, 1.3-disubstituted-prop-2-en-1-ones of type R 1COCH=CHR 2, exhibit a wide range of biological activities, particularly when they incorporate functionalized substituents; these include anti­cancer (Murthy et al., 2013 ▸), anti­malarial (Mishra et al., 2008 ▸; Yadav et al., 2012 ▸), anti­tripanosomal (Carvalho et al., 2012 ▸) and anti­viral (Sharma et al., 2011 ▸) activities. With these properties in mind, we have developed a versatile and efficient route to functionalized chalcones, which are themselves the basis for further elaboration to provide a wide range of multiply substituted chalcones. Here we report the synthesis and characterization of five 3-(5-ar­yloxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(4-(prop-2-yn-1- yloxy)phen­yl)prop-2-en-1-ones (I) and a corresponding series of five 1-(4-azido­phen­yl)-3-(3-methyl-1-phenyl-5-(ar­yloxy)-1H-pyrazol-4-yl)-prop-2-en-1-ones (II), together with the structures of a representative selection of three examples of each type, namely (Ib), (Ic) and (Ie) and (IIa), (IId) and (IIe) (Figs. 1 ▸–6 ▸ ▸ ▸ ▸ ▸). The compounds of types (I) and (II) were prepared using a common synthetic scheme starting from the commercially available 3-methyl-1-phenyl-1H-pyrazole, which was readily converted, under Vilsmaeier–Haack conditions, to the key precursor 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde (A) (Fig. 7 ▸), which was then converted to a series of 5-ar­yloxy derivatives (B), by reaction with substituted phenols under basic conditions as previously described (Kiran Kumar et al., 2019 ▸). The 5-ar­yloxy compounds (B) were then condensed with 1-[4-(prop-2-yn-1-yl­oxy)phen­yl]ethan-1-one to give the products (Ia)–(Ie) (Fig. 7 ▸) or with 1-(4-azido­phen­yl)ethan-1-one to give the corresponding series of products (IIa)–(IIe). Thus the synthesis of these two matched series of products (I) and (II) from common precursors, is highly efficient. The presence of the alkyne unit in the type (I) products and of the azido unit in the type (II) products means that a small library is now available for use in Huisgen-type cyclo­addition reactions to form bis­(chalcone)-substituted 1,2,3-triazoles. Such highly functionalized triazoles are an attractive synthetic target as 1,2,3-triazoles, which exhibit a very wide range of biological activity of potential medicinal values (Kharb et al., 2011 ▸; Dheer et al., 2017 ▸).

Structural commentary

Compounds (Ib) and (Ic) are geometrical isomers (Figs. 1 ▸ and 2 ▸), although they are not isomorphous (Table 3 ▸). Although the constitutions of compounds (Ie) and (IIe) differ only in the identity of the small substituent at atom C14 (Figs. 3 ▸ and 6 ▸), these compounds crystallize in different space groups (Table 3 ▸).

In each of the compounds reported here, the central core of the mol­ecules, comprising the pyrazole ring and the adjacent prop-2-en-1-one unit is very nearly planar. However, the three substituents at atoms C1, N31 and C35 (Figs. 1 ▸–6 ▸ ▸ ▸ ▸ ▸) are all twisted out of the plane of the mol­ecular core, as indicated by the relevant torsional angles (Table 1 ▸). None of the mol­ecules, therefore, exhibits any inter­nal symmetry, so that all are conformationally chiral: however, the space groups confirm that they have all crystallized as conformational racemates. In each case, the reference mol­ecule was selected to be one having a positive sign for the torsional angle N32—N31—C311—C312 (Table 1 ▸).

In compound (IId), the 2,4-di­chloro­phen­oxy substituent was found to be disordered over two sets of atomic sites, having occupancies 0.55 (4) and 0.45 (4) (Fig. 5 ▸). The disorder involves slight differences in the torsional angles around the bond C35-O351 (Fig. 5 ▸), thus C34—C35—O351—Cx51 = 78.3 (16)° when x = 3, and 65.0 (12)° when x = 4: on the other hand, the torsional angles around the bonds O351—Cx51 (x = 3 or 4) are the same within experimental uncertainty, thus C35—O351—Cx51—Cx52 = −164 (2)° for x = 3 and −163.6 (18)° when x = 4.

The orientation of the OCH2CCH substituent relative to the adjacent aryl ring is different in compound (Ib), as compared with (Ic) and (Ie) (Table 1 ▸, Figs. 1 ▸–3 ▸ ▸) and similarly the orientation of the azido substituent is different in (IId), as compared with (IIa) and (IIe). In the case of the type (I) compounds, it is tempting to associate the observed differences with the different patterns of hydrogen bonding (Table 2 ▸, and Section 3, below), where atom O14 acts as an acceptor only in (Ib) while atom C19 acts as a donor in (Ic) and (Ie) but not in (Ib). However, in none of the type (II) compounds do any of the N atoms of the azido unit act as a hydrogen-bond acceptor. Hence, in these compounds, at least, the role of this substituent may be mainly that of a space filler, with the conformation adopted being that which most effectively fills any available space between the mol­ecules.

Supra­molecular features

The supra­molecular assembly in the structures reported here is dominated by C—H⋯O hydrogen bonds (Table 2 ▸), along with C—H⋯π(arene) hydrogen bonds in compounds (Ic), (Ie) and (IIe). However, in none of the compounds containing chloro­phen­oxy substituents, [(Ib), (Ic) and (IId)] are there any short C—Cl⋯π(arene) contacts (cf. Imai et al., 2008 ▸).

There are two C—H⋯O hydrogen bonds in the structure of compound (Ib) (Table 2 ▸), and together these link the mol­ecules into a chain of centrosymmetric rings running parallel to the [010] direction, with rings of (20) type (Etter, 1990 ▸; Etter et al., 1990 ▸; Bernstein et al., 1995 ▸) centred at (1, n + 0.5, 0.5) alternating with rings of (30) type centred at (1, n, 0.5), where n represents an integer in each case (Fig. 7 ▸). In addition to an intra­molecular C—H⋯π(arene) hydrogen bond (Table 2 ▸), the structure of compound (Ic), isomeric with (Ib), contains two hydrogen bonds, one each of C—H⋯O and C—H⋯π(arene) types. The C—H⋯O hydrogen bond links mol­ecules related by translation into a C(11) running parallel to the [110] direction, and inversion-related pairs of such chains are linked by the C—H⋯π(arene) hydrogen bond to form a chain of rings running parallel to [110] (Fig. 8 ▸). Although there are no intra­molecular hydrogen bonds in the structure of compound (Ie), the inter­molecular hydrogen bonds (Table 2 ▸) are similar to those in compound (Ic), although the C—H⋯π(arene) inter­action involves a different donor atom; again a chain of rings is formed, but this time it runs parallel to the [10] direction (Fig. 9 ▸).

The only direction-specific inter­molecular contact in compound (IIa) involves a methyl group. Because such groups CH3—E generally undergo rapid rotation about the C—E bonds, even in the solid state (Riddell & Rogerson, 1996 ▸, 1997 ▸), particularly when, as here, the methyl group is bonded to a unit having local C 2 (mm2) symmetry, when the rotational barrier is particularly low (Tannenbaum et al., 1956 ▸; Naylor & Wilson, 1957 ▸). Accordingly, such a contact is not regarded as structurally significant. There is a single C—H⋯O hydrogen bond in the structure of compound (IId), with fairly similar dimensions for each of the two disorder components. Hence it is necessary to consider only the major disorder component, where the inversion-related pairs of mol­ecules are linked into cyclic, centrosymmetric (20) dimers (Fig. 10 ▸). In the structure of compound (IIe), inversion-related pairs of mol­ecules are linked by paired C—H⋯O hydrogen bonds to form cyclic, centrosymmetric (20) dimers, which in turn are linked into a chain of rings running parallel to the [100] direction (Fig. 11 ▸) by the combined action of two C—H⋯π(arene) hydrogen bonds, which utilize both rings of the 2-naphthyl substituent as the acceptors.

Hydrogen bonds are drawn as dashed lines and, for the sake of clarity, the unit-cell outline, the minor disorder component and the H atoms not involved in the motifs shown have been omitted. The atoms marked with an asterisk (*) are at the symmetry position (1 − x, 2 − y, 1 − z).

Figure 11

Thus, the supra­molecular assembly in the isomeric pair of compounds (Ib) and (Ic) is different in terms of the hydrogen bonds involved (Table 2 ▸), although chains of rings, different in each case, are found in all three of the type (I) compounds. Amongst the type (II) compounds, (IIa) and (IId) exhibit either no direction-specific inter­molecular inter­actions, as in (IIa), or finite, zero-dimensional aggregation, as in (IId). In (IIe), a chain of rings is again found, but different from those in any of the type (I) series, although the (20) motif can be identified in each of (Ib), (IId) and (IIe).

Database survey

The structures have recently been reported (Vinutha et al., 2014 ▸; Glidewell et al., 2019 ▸; Kiran Kumar et al., 2019 ▸) of a number of carbaldehyde precursors of type (B) (Fig. 12 ▸), including examples in which R = 2-chloro­phenyl, 4-chloro­phenyl and 2-naphthyl, i.e. the direct precursors for compounds (Ib), (Ic), (Ie), (IIb), (IIc) and (IIe). Structures have also been reported (Cuartas et al., 2017 ▸) for both an amino analogue of (B), namely 5-[benz­yl(meth­yl)amino]-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde and of the chalcone derived from this by condensation with 4-bromo­benzaldehyde; for the 5-(N-methyl­piperazino) analogue (Sunitha et al., 2016 ▸) and for the 5-piperidino analogue (Kiran Kumar, 2019 ▸). Finally, we note the structures of two isostructural 3-(5-ar­yloxy-3-methyl-1-phenyl-1H-pyrazole-1-yl)-1-thio­phen-2-yl)prop-2-en-1-ones, both of which exhibit disorder in the orientation of the thio­phene unit (Shaibah et al., 2020 ▸).

Synthesis and crystallization

For the preparation of the prop-2-yn-1-yl compounds (I), a solution of potassium hydroxide (0.31g, 5.7 mmol) in ethanol (30 ml) was added to a mixture of the appropriate inter­mediate of type (B, Fig.7), 5.7 mmol) and 4-(prop-2-yn-1-yl­oxy)aceto­phenone (1.0 g, 5.7 mmol) in ethanol (30 ml). The mixtures were then stirred at ambient temperature for 4 h, after which time, TLC indicated that the reactions were complete. The solid products were then collected by filtration, washed with water, dried in air and recrystallized from an ethanol–di­methyl­formamide (initial composition 3:1, v/v). Compound (Ia). Yield 82%, m.p. 551 K. IR (cm−1) 3228 (alkyne C-H), 2312 (alkyne C-C), 1672 (C=O), 1578 (C=N). MS (m/z) 449 (M+1)+. Compound (Ib). Yield 67%, m.p. 438 K.

For the preparation of the azido compounds (II), a solution of potassium hydroxide (0.34g, 6.2 mmol) in ethanol (30 ml) was added to a solution of 4-azido­aceto­phenone (1.0 g, 6.2 mmol) in ethanol (30 ml). The appropriate inter­mediate (B) (6.2 mmol) was then added and the mixtures were then stirred for 30 min, after which time TLC indicated that the reactions were complete. The solid products were then collected by filtration, washed with water, dried in air and recrystallized from an ethanol–di­methyl­formamide (initial composition 3:1, v/v). Compound (IIa).

Crystals of compounds (Ib), (Ic), (Ie), (IIa), (IId) and (IIe) which were suitable for single-crystal X-ray diffraction were selected directly from the prepared samples: despite repeated efforts, no crystal suitable for single-crystal X-ray diffraction have yet been obtained for compounds (Ia), (Id), (IIb) or (IIc).

Refinement

Crystal data, data collection and refinement details are summarized in Table 3 ▸. For a number of the structures, [(Ie), (IIa), (IId) and (IIe)], the diffraction data at values of θ > 25° were uniformly of very indifferent quality, particular in terms of the symmetry-equivalent reflections. This is probably a consequence of the indifferent crystal quality, exemplifying the general difficulty within the series (I) and (II) of growing crystals suitable for single-crystal X-ray diffraction (cf. Section 5, above). These higher-angle reflections were therefore rejected during the data-reduction process: we note also that the intensity statistics indicated that very few of these reflections were likely to be labelled as observed for compounds (Ie), (IIa), (IId) and (IIe). A number of low-angle reflections for (Ib) and (Ie) were also discarded at this stage because of attenuation by the beam stop. Some further low-angle reflections that had been attenuated by the beam stop were omitted from the data sets before the final refinements, thus: for (Ib) (101), (110), (002), (202) and (02); for (Ic) (10) and (002); for (Ie) (002), (111) and (012); for (IIa) (11); and for (IId) (12). In addition, the bad outlier reflections (04) for (Id) and (130) for (IIe) were also omitted. All H atoms were located in difference maps and then treated as riding atoms in geometrically idealized positions with C—H distances 0.93 Å (aromatic), 0.96 Å (CH3) or 0.97 Å (CH2), and with U iso(H) = kU eq(C), where k = 1.5 for the methyl groups which were permitted to rotate but not to tilt, and 1.2 for all other H atoms. The final difference map for compound (Ie) contained two significant peaks, 0.85 e Å−3 at (0.227, 0.557, 0.598), and 0.81 e Å−3 at (0.380, 0.488, 0.596), respectively 1.27 and 1.14 Å from atom C351: however, attempts to develop a plausible disorder model based upon these two peaks were not fruitful. For the minor disorder compound in compound (IId), the bonded distances and the [1,3] non-bonded distances were restrained to be the same as the corresponding distances in the major disorder component, subject to s.u. values of 0.01 and 0.02 Å, respectively. In addition, similarity restraints were applied to the anisotropic displacement parameters of the partial-occupancy atoms in the disorder components. Subject to these conditions, the occupancies for the two disorder components refined to values of 0.55 (4) and 0.45 (4). Examination of the final refined structures using PLATON (Spek, 2020 ▸) showed that the structure of compound (IIa) contained a void space, of volume 64 Å3, centred at (0.5, 0, 0), but further examination of this structure using the SQUEEZE procedure (Spek, 2015 ▸) showed that the void contained negligible electron density, consistent with the final difference map.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
