3-(1-Hydroxyethylidene)-1-phenylpyrrolidine-2,4-dione.
Analysis of C(12)H(11)NO(3) revealed a coplanar N-substituted phenyl group on a pyrrolidine ring with two keto moieties and a hydroxyethylidene functionality. The hydroxy group forms part of a hydrogen-bonding network characterized by a short intramolecular H.O distance of 1.81 (3) A, and a longer intermolecular interaction with an H.O distance of 2.38 (3) A. Both keto groups form additional intra- and intermolecular C-H.O contacts with H.O distances ranging from 2.26 to 2.41 A.
