摘要：

Crystals of two interconvertible, diastereomeric N‐methoxy‐3, 3‐di‐methoxy‐carbonyl‐5‐cyano‐1, 2‐oxazolidines have been examined by X‐ray analysis. The lower melting isomer, m.p. 55°, is shown to have trans configuration of the methoxy and cyano substituents. Some features of the molecular topography are discussed.
