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...π 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.
