چکیده
The asymmetric unit of the title compound, C(28)H(21)NO(3)S, contains two mol-ecules with similar geometries. The thia-zolidine rings adopt half-chair conformations while the pyrrolidine and the diketo-substituted five-membered carbocyclic rings are in envelope conformations with the spiro C atoms at the flaps. In one mol-ecule, the phenyl ring forms dihedral angles of 57.76 (12) and 71.79 (12)° with the fused benzene rings and the fused benzene rings form a dihedral angle of 57.75 (13)°. The corresponding dihedral angles in the other mol-ecule are 60.04 (12), 72.93 (12) and 54.51 (13)°. The mol-ecular structure is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds into layers lying parallel to the ab plane.
