Abstract
The present invention relates to a method and catalysts for the stereoselective addition of a nucleophile to a reactive &pgr;-bond of a substrate. The chiral, non-racemic catalysts of the present invention constitute the first examples of catalysts for nucleophilic additions that comprise a main-group metal and a tri- or tetra-dentate ligand.
