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.
通过 4-甲氧基衍生物的区域选择性取代,然后色谱分离衍生自 N-2-外-甲氧基-的非对映体,提供了从母体杂环获得多种 4-取代 2-恶唑烷酮的两种对映体的通用且实用的途径。 1-阿朴烷羰基化。
