for functional chiral molecules. An enantioselective synthesis of chiral spirobilactams via a copper‐catalyzed double N‐arylation was developed. Amplification of solution ee by in situ precipitation of the racemate was observed with this method and enantioenriched spirobilactams were obtained with excellent ee values through simple solid–solution phase separation.
螺环结构是功能性手性分子的通用构建基块。通过
铜催化的双N-芳基化反应,开发了对映体选择性的手性螺双内酰胺。通过这种方法观察到外消旋物的原位沉淀可放大溶液ee,通过简单的固溶相分离可得到对映体富集的螺双内酰胺,其ee值极佳。
