摘要

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??. 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-omers via pairs 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 the ab plane.

丁-4-基苄基]乙酸苄酯]中,恶唑烷环是平面的,具有r.m.s。偏差为0.03 ??。苄基环几乎垂直于恶唑烷环,二面角为80.11°(12)°。在晶体中,反式二聚体通过一对NH 3 O氢键在1-对映体和d-对映体之间形成。这种布置对于固态的化合物的聚合是有利的。二聚体通过CHOH氢键连接,形成平行于ab平面的层。
