1'-Allyl-1-(3,4-di­methyl­benzo­yl)-2-(4-methyl-1,3-thia­zol-5-yl)-1,2,5,6,7,7a-hexa­hydro­spiro­[pyrrolizine-3,3'-indolin]-2'-one

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 methyl­thia­zole ring is 25.95 (8)°. An intra­molecular C-H...O inter­action closes an S(8) ring. In the crystal, mol­ecules are linked by C-H...O inter­actions, generating C(11) chains propagating in [001].
