Abstract

The asymmetric unit of the title compound, C9H15NO4, consists of a functionalized pyrrolidine ring having an envelope conformation, synthesized as an ethyl ester. The mol-ecule has three chiral centres and crystallized as a racemic mixture. In the crystal, mol-ecules are linked by pairwise O-H⋯O bonds, generating dimers with twofold rotational symmetry.

Keywords: crystal structure; hydrogen bonds; oxopyrrolidine; ring conformation.
