Novel enamine-metal Lewis acid bifunctional catalysts were successfully applied to the asymmetric Michael addition of ketones to alkylidene malonates, offering excellent stereoselectivity (up to >99% ee and >99:1 dr). The asymmetric Michael addition of ketones to allylidene malonates was also achieved.
新型烯胺-金属 Lewis 酸双功能催化剂成功应用于酮与亚甲基丙二酸酯的不对称迈克尔加成反应,具有优异的立体选择性(高达>99%ee 和>99:1dr)。酮与烯丙基丙二酸酯的不对称迈克尔加成反应也得以实现。
