is considerable interest in the development of catalyzed enantioselective enolate-electrophile bond constructions to complement existing procedures which typically employ stoichiometric chiral controllers. In the design of these catalytic processes it would be highly desirable to merge the enolization event with the desired enantioselective bond construction. Catalyzedâ-ketoester conjugate additions
