RESUMO

The title compound, C(23)H(17)ClN(2)O(3)·C(2)H(6)O, is the stoichiometric 1:1 ethanol solvate of a racemic reaction product, which forms a conglomerate. The refined Flack parameter of 0.36 (3) indicates racemic twinning. In the structure, mol-ecules are linked into zigzag chains by a series of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.

RESUMO

The title heterocyclic compound, C(20)H(17)NO(3)S, was synthesized by condensation of ethyl cyano-acetate with (Z)-2-benzyl-idenebenzo[b]thio-phen-3(2H)-one in the presence of a basic catalyst in ethanol. The phenyl and ester groups make dihedral angles of 77.67 (6) and 8.52 (6)°, respectively, with the benzothienopyran ring system [maximum r.m.s. deviation = 0.1177 (13) Å]. In the crystal, centrosymmetric dimers are formed through pairs of N-H⋯O hydrogen bonds between the amine and ester groups. Inter-molecular C-H⋯N hydrogen bonds and C-H⋯π inter-actions involving the thio-phene ring are also observed.

RESUMO

In the title compound, C(23)H(17)NO(3)S, the thio-phene and isoxazole rings each have an envelope conformation with the spiro C atom linking them forming the flap of the envelope in each case. The dihedral angle between the mean planes of the benzothio-phene ring and isoxazole rings is 81.35 (7)°. In the crystal, an inter-molecular C-H⋯O hydrogen bond links the mol-ecules into a chain running parallel to the a axis.
