Chiral (salen)Al complex 1a catalyzes the highly enantioselective conjugate addition of carbon- and nitrogen-based nucleophiles to acyclic alpha,beta-unsaturated ketones. This methodology is tolerant of substantial variation of the ketone structure, providing access to a wide range of useful chiral building blocks in high yield and enantiomeric excess. Synthetic manipulations of the conjugate addition products are demonstrated, including the straightforward preparation of beta-amino ketones and highly enantio-enriched carbo- and heterocyclic compounds.
