Crystal structure of dimethyl 1-oxo-2,4-di-phenyl-1,2-dihydronaphthalene-2,3-di-carboxyl-ate.

In the title compound, C26H20O5, a 1,2-di-hydro-naphthalene derivative, the cyclo-hexa-1,3-diene ring of the 1,2-di-hydro-naphthalene ring system adopts a half-chair conformation. The mean plane of the 1,2-di-hydro-napthalene ring system makes dihedral angles of 86.23 (6) and 64.80 (7)° with two phenyl rings. The carbonyl O atom attached to the di-hydro-naphthalene ring system deviates from the mean plane of the 1,2-di-hydro-naphthalene ring system by 0.618 (1) Å. In the crystal, the mol-ecules are linked into layers parallel to the bc plane via two kinds of C-H⋯O inter-actions, one of which forms a C(10) chain motif running along the c-axis direction and the other forms an R22(6) ring motif. Adjacent layers are further connected by C-H⋯π and offset π-π inter-actions [centroid-centroid distance = 3.6318 (9) Å].

Chemical context

Naphthalene derivatives have manifested applications in many fields, for example, as colorants, explosives, disinfectants, insecticides and the plant hormone auxin. Naphthalene is believed to play a role in the chemical defence against biological enemies (Wiltz et al., 1998 ▸; Wright et al., 2000 ▸). Naphthalene derivatives have been identified as a new range of potent anti-microbials that are effective against a wide range of human pathogens and have diverse and inter­esting anti­biotic properties with minimum toxicity (Rokade & Sayyed, 2009 ▸; Upadhayaya et al., 2010 ▸). Compounds with non-coplanarly accumulated aromatic rings have received attention from organic chemists and materials chemists as unique structural building blocks, because they provide characteristic optical and electronic properties originating from their structural features. For example, biphenyl and binaphthyl are applied to optically active mol­ecular catalysts and polymer materials on the basis of their axial chiralities (Deria et al., 2013 ▸). The structures of similar 1-oxo-1,2-di­hydro­naphtalene derivatives, namely, dimethyl 4-(4-meth­oxy­phen­yl)-2-(4-methyl­phen­yl)-1-oxo-1,2-di­hydro­naphthalene-2,3-di­carboxyl­ate, dimethyl 1-oxo-2-(pyren-4-yl)-4-(thio­phen-2-yl)-1,2-di­hydro­naphthalene-2,3-di­carboxyl­ate and ethyl 1-oxo-2-phen­yl-2,4-bis­(thio­phen-2-yl)-1,2-di­hydro­naphthalene-3-carboxyl­ate, have been reported by Gopinath et al. (2017 ▸).

Structural commentary

In the title compound (Fig. 1 ▸), the 1,2-di­hydro­naphthalene C1–C10 ring system is not strictly planar and the cyclo­hexa-1,3-diene C5–C10 ring adopts a half-chair conformation with puckering and smallest displacement parameters q 2 = 0.3091 (14) Å, q 3 = 0.1461 (14) Å, φ2 = 155.9 (3)° and θ = 64.7 (2)° and ΔCs = 4.41 (19). The dihedral angle between the C1–C6 and C5–C10 rings is 10.15 (6)°. The C11–C16 phenyl ring is almost perpendicular to the 1,2-di­hydro­naphthalene C1–C10 ring system with a dihedral angle of 83.83 (7)° between them. The other phenyl ring (C21–C26) makes dihedral angles of 64.80 (7) and 29.06 (8)° with the mean plane of C1–C10 ring system and the C11–C16 phenyl ring, respectively. Atom O1 of the carbonyl group deviates from the mean plane of the 1,2-di­hydro­naphthalene ring system by 0.647 (1) Å.

Supra­molecular features

In the crystal, the mol­ecules are linked via C—H⋯O hydrogen bonds (C24—H24⋯O2i; symmetry code as in Table 1 ▸), which generates C(10) zigzag chains running along the c-axis direction (Fig. 2 ▸). In addition, the chains are linked via pairs of C—H⋯O inter­actions (C20—H20B⋯O5ii; Table 2 ▸) with an (6) ring motif (Fig. 3 ▸), forming layers parallel to the bc plane. Between the layers there are also C—H⋯π (C3—H3⋯Cg3iii; Table 1 ▸) and π–π stacking inter­actions (Fig. 4 ▸) [Cg1⋯Cg1iii = 3.6318 (9) Å, inter­planar distance = 3.343 (1) Å and offset distance = 1.419 (1) Å; symmetry code: (iii) −x, 1 − y, −z; Cg1 and Cg3 are the centroids of the C1–C6 and C11–C16 rings, respectively].

Synthesis and crystallization

To a solution of 1,3-di­phenyl­isobenzo­furan (1 g, 3.70 mmol) in dry di­chloro­methane, dimethyl acetyl­enedi­carboxyl­ate (0.58 g, 4.07 mmol) was added and the reaction mixture was stirred at room temperature for 1 h. Removal of solvent followed by column chromatographic purification (silica gel; 15% ethyl acetate in hexa­ne) afforded isobenzo­furan­dimethyl acetyl­enedi­carboxyl­ate adduct as a colourless solid (1.10 g, 72%). To a solution of the adduct (0.50 g, 1.21 mmol) in dry di­chloro­methane, BF3·OEt2 (0.075 g, 0.52 mmol) was added and the reaction mixture was stirred at room temperature for 5 min. Removal of solvent followed by column chromatographic purification (silica gel; 15% ethyl acetate in hexa­ne) gave the title compound as a colourless solid (0.45 g, 94%). Single crystals suitable for X-ray diffraction were prepared by slow evaporation of an ethyl acetate solution of the title compound at room temperature (m.p. = 454–456 K).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms were localized in a difference-Fourier map and then were treated as riding atoms, with C—H = 0.93 and 0.96 Å for aryl and methyl groups, respectively, and with U iso(H) = 1.2U eq(aryl C) and 1.5U eq(methyl C), allowing for free rotation of the methyl groups.

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.
