Highly Enantioselective Catalytic Conjugate Addition of N‐Heterocycles to α,β‐Unsaturated Ketones and Imides

New nucleophiles in the arena of asymmetric catalysis, fused and nonfused N-heterocycles undergo conjugate addition to unsaturated imides and enones in the presence of a chiral [(salen)AlIII] complex with generally high enantioselectivities (see scheme; salen=N,N′-bis(salicylaldehydo)ethylenediamine).
