  • Title: Merging chiral organocatalysts: enantio- and diastereoselective direct vinylogous Mannich reaction of alkylimines.
    Author: Xiong XF, Jia ZJ, Du W, Jiang K, Liu TY, Chen YC.
    Journal: Chem Commun (Camb); 2009 Dec 07; (45):6994-6. PubMed ID: 19904372.
    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.
