(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

In the title compound C(37)H(32)Cl(2)N(2)O(4), the unsubstituted pyrrolidine ring shows a twist conformation whereas the substituted pyrrolidine ring shows an envelope conformation. The dimeth­oxy benzene ring is perpendicular to the tetra­lone ring, making a dihedral angle of 89.94 (5)°. Mol­ecules are linked into centrosymmetric dimers by N—H⋯O hydrogen bonds and the crystal structure is stabilized by C—H⋯π inter­actions and C—H⋯O hydrogen bonds. One meth­oxy group is disordered over two positions with the site occupancy factors of 0.84 (2) and 0.16 (2).
