(1′S)-4-(3,4-Dichlorophenyl)-1′-(3,5-dimethoxyphenyl)-1,2,3, 4-tetrahydronaphthalene-2-spiro-2′-pyrrolizidine-3′-spiro-3″- indoline-1,2″-dione

Abstract

In the title compound C37H32Cl2N 2O4, the unsubstituted pyrrolidine ring shows a twist conformation whereas the substituted pyrrolidine ring shows an envelope conformation. The dimeth-oxy benzene ring is perpendicular to the tetra-lone ring, making a dihedral angle of 89.94 (5)°. Mol-ecules are linked into centrosymmetric dimers by N - H⋯O hydrogen bonds and the crystal structure is stabilized by C - H⋯π inter-actions and C - H⋯O hydrogen bonds. One meth-oxy group is disordered over two positions with the site occupancy factors of 0.84 (2) and 0.16 (2).
