Merging chiral organocatalysts: enantio- and diastereoselective direct vinylogous Mannich reaction of alkylimines

Chem Commun (Camb). 2009 Dec 7:(45):6994-6. doi: 10.1039/b917408g. Epub 2009 Oct 8.

Abstract

An enantio- and diastereoselective direct vinylogous Mannich reaction of alpha,alpha-dicyanoolefins and N-sulfonyl alkylimines has been developed by the catalysis of a new family of bifunctional organocatalysts merging chiral BINOL and 9-amino-9-deoxyepi-cinchona alkaloid skeletons, from which chiral beta-, delta- or gamma-amino compounds could be efficiently derived.
