Methyl 3′-benzyl-4′-(2-chlorophenyl)-1′-methyl-2-oxospiro[indoline-3,2′-pyrrolidine]-3′-carboxylate
Abstract
In the title compound, C27H25ClN2O3, the methylpyrrolidine ring adopts an envelope conformation with the N atom at the flap. The mean plane of the pyrrolidine ring makes dihedral angles of 82.1 (1), 84.4 (1) and 79.8 (1)°, respectively, with the adjacent benzene ring, the mean plane of the indoline ring system and the phenyl ring. The molecular structure is stabilized by intramolecular C—H...O hydrogen bonds. In the crystal, molecules are linked into chains along [101] by N—H...O hydrogen bonds. C—H...π interactions are observed between the chains.
