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.
