Simple and efficient: The first highly enantioselective aza‐Morita–Baylis–Hillman reaction between acrylonitrile and imines has been developed. Excellent yields and enantioselectivities were observed for the reaction of various imines using chiral phebim/PdII complexes (1; see scheme). This process offers a simple and efficient route for the synthesis of functionalized α‐methylene‐β‐aminonitriles and
