Abstract

In the title compound, C30H31N3O2S, the fused pyrrolidine ring bearing three substituents adopts an envelope conformation with the C atom bearing the benzoyl group as the flap. The other fused pyrrolidine ring adopts a twisted conformation about one of its C-C bonds. The dihedral angle between the isatin ring system and the methyl-thia-zole ring is 25.95 (8)°. An intra-molecular C-H⋯O inter-action closes an S(8) ring. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating C(11) chains propagating in [001].
