Abstract

The catalytic enantioselective reaction of α-phenylthioacetonitriles with imines has been developed. The reaction of various imines proceeds in good yields and diastereo- and enantioselectivities in the presence of chiral bis(imidazoline)-palladium catalysts. The obtained products can be converted into β-aminonitrile or β-aminoamide compounds without loss of enantiopurity.
