efficient enantioselective hydrogenation of 1,2-dicyanoalkenes catalyzed by the complex of rhodium and f-spiroPhos has been developed. A series of 1,2-dicyanoalkenes were successfully hydrogenated to the corresponding chiral 1,2-dicyanoalkanes under mild conditions with excellent enantioselectivities (up to 98% ee). This methodology provides efficient access to the asymmetric synthesis of chiral diamines
已经开发了由铑和f-spiroPhos的配合物催化的1,2-二氰基烯烃的高效对映选择性氢化。在温和的条件下,以优异的对映选择性(高达98%ee)将一系列1,2-二氰基烯烃成功氢化为相应的手性1,2-二氰基烷烃。该方法提供了有效的手性二胺不对称合成途径。
