Abstract: The asymmetric unit of the title compound, C₁₄H₁₇NO₄·1.25H₂O, consists of four substituted pyrrolidone molecules (two pairs of enantiomers) and five water molecules. The five-membered rings each have an envelope conformation, with the C atom bonded to the ester group as the flap. The mean planes of the five-membered rings of the four pyrrolidone molecules make dihedral angles of 60.87 (5), 64.45 (5), 62.03 (5) and 65.79 (5)° with respect to the phenyl rings. In the crystal, the pyrrolidone and water molecules are connected through O-HO hydrogen bonds, forming a layer parallel to the ab plane. The two-dimensional network is further stabilized by intermolecular C-HO hydrogen bonds.
