A highly enantioselective method for catalytic reductive coupling of alkynes and aldehydes afforded allylic alcohols with complete E/Z selectivity, generally >95:5 regioselectivity, and in up to 96% ee. In conjunction with ozonolysis, this process allows the enantioselective synthesis of α-hydroxy ketones.
