7′-4-(Trifluoro­meth­yl)phen­yl-5′6′7′7a’-tetra­hydrodispiro­indan-25′-pyrrolo­12-c13thia­zole-6′2′′-indan-131′′-trione

摘要

In the title compound, C29H20F3NO3S, the thia­zolidine ringadopts a half-chair conformation. The pyrrolidine and two five-membered carbocyclic rings are in envelope conformations with the spiro C atoms at the flaps. The trifluoro­methyl-substituted benzene ring forms dihedral angles of 62.37 (14) and 87.40 (14)° with the benzene rings of the dihydro-1H-indene units. The two benzene rings form a dihedral angle of 36.94 (15)°. The mol­ecular structure is stabilized by intra­molecular C—H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol­ecules are linked into inversion dimers by pairs of inter­molecular C—H⋯O hydrogen bonds, generating R 2 ²(10) ring motifs.
