Abstract

Michael addition amines asymmetric catalysis enones alkaloids
Synergy makes it possible: Bifunctional cinchona alkaloids are found to promote the first highly enantioselective organocatalytic aza‐Michael reactions with α,β‐unsaturated ketones. In addition to utilizing practical catalysts, readily accessible substrates, and commercially available reagents, this reaction affords a synthetically valuable scope that is complimentary to existing methods catalyzed by chiral metal complexes.
