Methyl 2-(2-hydroxybenzylideneamino)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate
Abstract
In the title compound, C17H17NO3S, the cyclohexene ring is essentially planar, with a maximum deviation of 0.006 (1) Å. The cyclohexene ring adopts a half-chair conformation. The dihedral angle between the thiophene and benzene rings is 29.7 (1)°. The molecular structure exhibits intramolecular O—H...O, O—H...N and C—H...S hydrogen bonds, which generate one S(5) and two S(6) motifs. There is also a C—H...π interaction between the cyclohexene ring system and the π-system of the benzene ring.
