Enantioselective Addition of Dialkylzincs to Aldehydes Using Heterogeneous Chiral Catalysts Immobilized on Alumina and Silica Gel

Article abstract of DOI:10.1021/jo00303a014

The first example of the use of alumina and silica gel as insoluble supports for the chiral catalyst in the enantioselective addition of dialkylzincs to aldehydes is described.Chiral N-alkylnorephedrines were immobilized on (3-chloropropyl)silyl-functiona
