A rhodium complex bearing a chiral phosphite ligand catalyzes the hydrosilylation of β,β-disubstituted enamides to afford valuable α-aminosilanes in a highly regio-, diastereo-, and enantioselective manner. Stereodivergent synthesis is achieved by regulating substrate geometry and ligand enantiomer to generate all the possible stereoisomers in high enantio-purity.
