Abstract
In the title compound, C7H9NO5, alternative nameN-carboxy-L-glutamic anhydride γ-methyl ester, the oxazolidine ring is essentially planar with a maximum deviation of 0.020 (3) Å. In the crystal, molecules are linked by N—H...O hydrogen bonds between the imino group and the carbonyl O atom in the methyl ester group, forming a tape structure along thea-axis direction. The tapes are linked by C—H...O interactions into a sheet parallel to theacplane. The tapes are also stacked along thebaxis with short contacts between the oxazolidine rings [C...O contact distances = 2.808 (4)–3.060 (4) Å], so that the oxazolidine rings are arranged in a layer parallel to theabplane. This arrangement of the oxazolidine rings is very preferable for the polymerization of the title compound in the solid state.
