Abstract top

The asymmetric unit of the title compound, C23H16OS, contains two independent molecules with opposite orientations of the methoxy groups bonded to the benzene rings. The napthobenzothiophene group in the two molecules is separated by an average distance of 3.912 Å. In both molecules, the napthobenzothiophene unit is almost planar, with r.m.s deviations of 0.0522 and 0.0143 Å. The methoxyphenyl ring makes dihedral angles of 67.0 (6)° and 70.4 (6)° with respect to the napthobenzothiophene ring system in the two molecules. The crystal packing features C-H...S, [pi]-[pi] [centroid-centroid distances = 3.666 (10) and 3.658 (10) Å] and C-H...[pi] interactions, forming a sheet running along the b-axis direction.

Comment top

Thiophene derivatives exhibit anti-Human immunodeficiency virus protease (HIVPR) (Bonini et al., 2005) and anti-breast cancer (Brault et al., 2005) activities. In addition, some of the benzo[b]thiophene derivatives show significant antimicrobial and anti-inflammatory activities (Isloora et al., 2010). The thiophene derivatives have been viewed as significant compounds for application in many fields (Xia et al., 2010). In order to obtain detailed information on molecular conformations in the solid state, X-ray crystallographic study of the title compound was carried out.

An asymmetric unit of the title compound contains two crystallographically independent molecules with opposite orientations of the methoxy groups (Fig. 1). The bond lengths and angles agree with those observed in another benzothiophene derivative (Gunasekaran et al., 2010). In both the molecules, napthobenzothiophene ring system is essentially planar, with maximum deviation of 0.103 (2) and 0.024 (1) Å for atoms C21 and S1', respectively. In both molecules, the napthobenzothiophene ring system (S1/C8—C23 and S1'/C8'-C23') makes dihedral angles of 67.0 (6)° and 70.4 (6)° with respect to benzene rings (C2–C7) and (C2'–C7'), respectively; showing that both the ring system are almost perpendicular to each other.

The π···π electron interactions are observed between the thiophene ring (S1/C16—C19 [at x, y, z] and the benzene ring (C9—C14) [at -1 + x, y, z] with centroid-centroid distance 3.666 (10) Å and between the thiophene ring (S1'/C16'–C19' [at x, y, z] and the benzene ring (C9'–C14') [at 1 + x, y, z] with the centroid-centroid distance 3.658 (10) Å. In addition the crystal packing is stabilized by C–H···S and C–H···π (Table. 1) types of interactions.

Experimental top

Benzo[b]thiophen-3-yl(2-((4-methoxyphenyl)pivaloyloxy)methyl)phenyl)methyl pivalate (0.73 g, 1.60 mmol) upon interaction with ZnBr2 (0.02 g, 0.13 mmol) followed by removal of solvent and column chromatographic purification (silica gel; hexane-ethyl acetate, 99:1) gave the compound as a colorless solid (0.50 g, 72%); the compound was recrystalized from chloroform.

Refinement top

All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances 0.93 and 0.96 Å for aryl and methyl H-atoms with Uiso(H) = 1.5Ueq(methyl-C) and 1.2Ueq(aryl-C).

Special details top

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