Desymmetrization of carbon nucleophiles by palladium-catalyzed asymmetric allylic alkylation has been realized for the first time. Products with three chiral centers were obtained in good yield and with high diastereo- and enantioselectivity. The method offers an efficient access to optically active tropane derivatives.
碳亲核试剂通过钯催化的不对称烯丙基烷基化反应的不对称化已首次实现。得到具有三个手性中心的产物,产率高,非对映和对映选择性高。该方法提供了有效的光学活性托烷衍生物的途径。
