In the title compound, C32H30N2O7, the piperidone ring adopts a chair conformation and the five-membered ring of the dihydro­indenone ring system adopts an envelope conformation. Intra­molecular O—H...N and C—H...O hydrogen bonds occur. The dihedral angle between the two hydr­oxy-subsituted methoxy­phenyl rings is 71.12 (5)°. In the crystal structure, mol­ecules are connected by inter­molecular O—H...O hydrogen bonds, forming layers parallel to (001). These layers are further connected by C—H...O hydrogen bonds, forming a three-dimensional network.

In the title compound, C32H26Cl2N2O3, the piperidone ring adopts a chair conformation and the proline and pyrrolidine rings adopt envelope conformations. The indane ring system is essentially planar with an r.m.s. deviation of 0.011 Å for the non-H atoms. The dihedral angle between the two chloro-substituted benzene rings is 63.69 (10)°. Intra­molecular C—H...O and N—H...O hydrogen bonds may influence the mol­ecular conformation. In the crystal structure, mol­ecules are connected into layers by weak inter­molecular C—H...O hydrogen bonds.
