A chiral spirocyclic quaternary ammonium saltcatalyzedasymmetric alkylation of unactivated amides under homogeneous conditions has been developed, giving the target products with up to 60% ee. This novel methodology provides a general and concise protocol for asymmetric α-functionalization of unactivated amides.
开发了一种手性螺环季铵盐催化非活化酰胺在均相条件下的不对称烷基化,得到目标产物的 ee 高达 60%。这种新颖的方法为未活化酰胺的不对称 α-功能化提供了一个通用而简洁的协议。
