摘要
The title compound, C(26)H(27)NO(4)S, with a thiophene ring fused to a quinoline ring, was synthesized via the condensation of dihydrothiophen-3(2H)-one 1,1-dioxide, 5,5-dimethyl-3-( phenylamino) cyclohex-2-enone and 3-methoxybenzaldehyde in refluxing ethanol. In the crystal structure, the thiophene dioxide ring and the pyridine ring adopt envelope conformations. The connection of the pyridine ring to the phenyl and benzene rings can be described by the C-C-C-C and C-N-C-C torsion angles of 45.5 (2) and 88.7 (2)degrees, respectively. The cyclohex-2-enone ring is in a half-chair conformation. The crystal packing is stabilized by non-classical intermolecular C-H center dot center dot center dot O hydrogen bonds with the carbonyl O and sulfone O atoms acting as acceptors.
