Crystal structure of methyl 6-meth-oxy-11-(4-meth-oxy-phen-yl)-16-methyl-14-phenyl-8,12-dioxa-14,15-di-aza-tetra-cyclo-[8.7.0.0(2,7).0(13,17)]hepta-deca-2(7),3,5,13(17),15-penta-ene-10-carboxyl-ate.

In the title compound, C30H28N2O6, the pyran ring adopts a slightly distorted half-chair conformation and the pyrone ring adopts an envelope conformation, with the C atom bearing the carboxyl-ate group as the flap. The pyrazole ring [maximum deviation = 0.002 (2) Å] forms a dihedral angle of 13.2 (1)° with the attached benzene ring. The near-planar atoms of the pyran ring and the pyrazole ring are close to coplanar, the dihedral angles between their mean planes being 6.4 (1)°. The dihedral angle between the pyrone ring and the benzene ring of the chromene unit is 10.7 (1)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, C-H⋯O inter-actions generate supra-molecular chains propagating in [100] and these are connected into double layers that stack along the c-axis direction by weak π-π inter-actions between pyrazole rings [centroid-centroid distance = 3.801 (1) Å].

Chemical context

Chromenes are components of many natural products (Ellis & Lockhart, 2007 ▶) and incorporated in numerous medicinal drugs as significant chromophores. They have shown to display anti­viral, anti­tumoral, anti-anaphylactic, spasmolytic, diuretic and clotting activity (Horton et al., 2003 ▶). Furthermore, they can be used as photo-active materials, biodegradable agrochemicals and pigments. As part of our studies in this area, the crystal structure of the title compound has been determined and the results are presented here.

Structural commentary

Fig. 1 ▶ shows a displacement ellipsoid plot of the title compound, with the atom-numbering scheme. The pyran ring (O1/C1/C3/C4/C5/C13) adopts a slightly distorted half-chair conformation, with the local twofold rotation axis running through the mid-points of bonds C3—C1 and C5—C4 [asymmetry parameter (Duax et al., 1976 ▶) ΔC 2[C3–C1] = 7.5 (2)°] The pyrone ring (O2/C5/C6/C7/C12/C13) adopts an envelope conformation, with the C5 [displacement = 0.347 (1) Å] atom as the flap and with puckering parameters q 2 = 0.3973 (2) Å and ϕ2 = 119.7 (2)°. The pyrazole ring is approximately planar, with a maximum deviation of 0.002 (2) Å for atom C2, and forms a dihedral angle of 13.2 (1)° with the attached benzene ring. The planar atoms of the pyran ring and the pyrazole ring are close to coplanar, the dihedral angles between their mean planes being 6.4 (1)°. Moreover, the planar atoms of the pyrone ring and the benzene ring of the chromene unit are also almost coplanar, the dihedral angle between their mean planes being 10.7 (1)°. The geometric parameters of the title mol­ecule agree well with those reported for similar structures (Kanchanadevi et al., 2013a ▶,b ▶).

Supra­molecular features

The mol­ecular conformation is stabilized by an intra­molecular C19—H19⋯O1 hydrogen bond, which generates an S(6) ring motif. The crystal packing features C17—H17⋯O3 hydrogen bonds, which form a supra­molecular chain along the a axis. This chain is connected into double layer that stacks along the c axis (Table 1 ▶ and Fig. 2 ▶; Cg is the centroid of the pyrazole N1/N2/C3/C1/C2 ring) by π–π inter­actions, with Cg⋯Cg ii = 3.801 (1) Å [symmetry code: (ii) −x, −y, −z].

Database survey

The title compound, (I), is closely related to 16-methyl-11-(2-methyl­phen­yl)-14-phenyl-8,12-dioxa-14,15-di­aza­tetra­cyclo[8.7.0.02,7.013,17]hepta­deca-2(7),3,5,13 (17),15-penta­ene-10-carbo­nitrile, (II) (Kanchanadevi et al., 2013a ▶), and methyl 11,14,16-triphenyl-8,12-dioxa-14,15-di­aza­tetra­cyclo[8.7.0.02,7.013,17]hepta­deca-2(7),3,5,13 (17),15-penta­ene-10-carboxyl­ate, (III) (Kanchanadevi et al., 2013b ▶). The pyran and pyrone rings of (II) and (III) adopt half-chair conformations, while the pyran and pyrone rings of (I) adopt half-chair and envelope conformations, respectively. The pyrazole ring forms dihedral angles of 13.2 (1), 16.9 (1) and 15.1 (1)°, respectively, for (I), (II) and (III) with the attached benzene ring.

Synthesis and crystallization

A mixture of (E)-methyl 2-[(2-formyl-6-meth­oxy­phen­oxy)meth­yl]-3-(4-meth­oxy­phen­yl)acrylate (0.356g, 1mmol) and 3-methyl-1-phenyl-1H-pyrazol-5-one (0.174 g, 1 mmol) was placed in a round-bottomed flask and melted at 453 K for 1 h. After completion of the reaction as indicated by thin-layer chromatography, the crude product was washed with 5 ml of an ethyl acetate and hexane mixture (1:49 ratio), which successfully provided the title compound as a colourless solid in 93% yield. Colourless blocks were obtained by slow evaporation of an ethyl acetate solution at room temperature.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▶. All the H atoms were positioned geometrically, with C—H = 0.93–0.98 Å, and constrained to ride on their parent atom, with U iso(H) = 1.5U eq(C) for methyl H atoms and 1.2U eq(C) for other H atoms. Owing to poor agreement, the reflections 100, 011 and 100 were omitted from the final cycles of refinement.

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
