title: Ethyl 2-cyano-5-oxo-5-(thio-phen-2-yl)-3-(3,4,5-trimeth-oxy-phen-yl)penta-noate.
abstract: In the title compound, C21H23NO6S, the dihedral angle between the thio-pene and benzene rings is 88.66 (6)°. In the crystal, mol-ecules are connected by C-H⋯N and C-H⋯O hydrogen bonds, forming a tape along [10-1]. In addition, C-H⋯π and π-π stacking [centroid-centroid distance = 3.879 (2) Å between the thio-phene rings] inter-actions are observed.
