enantioselective method for catalytic reductive coupling of alkynes and aldehydes is described. Allylicalcohols are afforded with complete E/Z selectivity, generally >95:5 regioselectivity, and in up to 96% ee. In conjunction with ozonolysis, this process is complementary to existing methods of enantioselective alpha-hydroxy ketone synthesis.
