通过经由4-甲氧基衍生物的区域选择性取代,然后通过色谱分离衍生自N-2-外-甲氧基-1-阿朴樟脑羰基化的非对映异构体,提供了从母体杂环得到多种4-取代的2-恶唑烷酮的两种对映异构体的通用和实用的路线。
A versatile and practical route to both enantiomers of a wide variety of 4-substituted 2-oxazolidinones from the parent heterocycle is provided by regioselective substitutions via 4-methoxy derivative followed by chromatographic separation of the diastereomers derived from N-2-exo-methoxy-1-apocamphanecarbonylation.
