Highly Enantioselective Alkenylation of Glyoxylate with Vinylsilane Catalyzed by Chiral Dicationic Palladium(II) Complexes

Abstract

Chiral dicationic palladium complex-catalyzed vinylation and dienylation of glyoxylate with vinylsilanes and dienylsilanes to produce highly optical active allylic alcohols has been achieved. The advantages of this reaction are that the chiral palladium catalyst is readily employed and that vinylsilanes as nucleophiles are easily synthesized, storable, and air- and moisture-stable.
