A chiral dicationic palladium complex-catalyzed vinylation and dienylation of glyoxylate with vinylsilanes and dienylsilanes produces highly optical active allylic alcohols. The chiral palladium catalyst is readily employed and vinylsilanes as nucleophiles are easily synthesized, storable, and air- and moisture-stable.
