✦ Synopsis
The title compound, C 28 H 22 ClNO 3 , has two crystallographically independent molecules in the asymmetric unit. The pyrrolidine ring (A) of the pyrrolizine system adopts an envelope conformation in both molecules, whereas the other five-membered ring (B) adopts an envelope conformation in one molecule and a twist conformation in the other. The molecular packing is stabilized by intermolecular C-HÁ Á ÁO, C-HÁ Á Á andinteractions.

The two pyrrolidine rings in the title compound, C~25~H~22~N~2~O~6~, adopt envelope conformations. Molecules are stabilized by intramolecular O—H...O hydrogen bonds, and linked into centrosymmetric dimers by intermolecular N—H...O hydrogen bonds.
