A direct, highly enantioselective alkylation of arylacetic acids via enediolates using a readily available chiral lithium amide as a stereodirecting reagent has been developed. This approach circumvents the traditional attachment and removal of chiral auxiliaries used currently for this type of transformation. The protocol is operationally simple, and the chiral reagent is readily recoverable.
已经开发出使用容易获得的手性氨基锂作为立体定向试剂通过烯二醇对芳基乙酸进行直接、高度对映选择性的烷基化。这种方法绕过了目前用于此类转化的手性助剂的传统附着和去除。该方案操作简单,手性试剂易于回收。
