Abstract: In the title compound, C18H14N2O5, the pyrrolidine ring adopts a shallow envelope conformation, with the C atom bearing the OH group (and remote from the N atom) displaced by 0.257 (2) Å from the other atoms. The cyclo­pentane ring has a twisted conformation about the C-C bond bearing one =O and one -OH grouping. The dihedral angle between the five-membered rings (all atoms) is 65.54 (9)° and the OH groups lie to the same side of the ring-junction. The mol­ecular structure features a weak intra­molecular O-H...O bond and a possible C-H...[pi] inter­action. In the crystal, the mol­ecules are linked into [010] chains by O-H...O hydrogen bonds. Weak C-H...O bonds connect the chains into (100) sheets.
