et al.

Abstract: A direct catalytic enantioselective alkynylation 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 terminal 1,3‐diynes are well tolerated. Furthermore, the catalytic reaction is applicable to preparation of bo… Show more
