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.
钯催化不对称烯丙基烷基化首次实现了碳亲核试剂的去对称化。产物具有三个手性中心,产率高,具有高非对映选择性和对映选择性。该方法为获得光学活性托烷衍生物提供了一种有效的途径。
