Crystal structure of β-benzyl dl-aspartateN-carb-oxyanhydride.
In the title racemic compound, C12H11NO5[systematic name: benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate], the oxazolidine ring is planar, with an r.m.s. deviation of 0.03 Å. The benzyl ring is almost normal to the oxazolidine ring, making a dihedral angle of 80.11 (12)°. In the crystal, inversion dimers are formed between the l- and d-enanti-omersviapairs of N-H⋯O hydrogen bonds. This arrangement is favourable for the polymerization of the compound in the solid state. The dimers are linked by C-H⋯O hydrogen bonds, forming layers parallel to theabplane.
