title: Organocatalytic asymmetric Michael addition of 1-acetylcyclohexene and 1-acetylcyclopentene to nitroolefins.
abstract: Enantioselective organocatalytic Michael addition reactions of 1-acetylcyclohexene, 1-acetylcyclopentene and 1-acetylcyclobutene to nitroolefins have been developed. This is the first report where an α-branched enone has been activated by an amine catalyst for the asymmetric Michael addition reaction to an electrophile. The Michael products have also been cyclized to bicyclic compounds.
