A direct catalytic enantioselectivealkynylation reaction of trifluoropyruvates with terminal 1,3-diynes was achieved by using C2-symmetric NCN pincer rhodium (III) complexes with bis(imidazolinyl)phenyl ligands. This protocol is effective for enantioselective synthesis of optically active trifluoromethylated tertiary alcohols with the diyne moiety. A variety of electronically and structurally diverse
