The enantioselective propargylic amination of propargylic pentafluorobenzoates bearing an alkyl group at the propargylic position with amines in the presence of catalytic amounts of a copper complex and an optically active diphosphine such as BINAP has been found to give the corresponding propargylic amines in good yields with high enantioselectivity.
在催化量的铜配合物和光学活性二膦(如BINAP)的存在下,发现在炔丙基位置带有烷基的炔丙基五氟苯甲酸酯与胺的对映选择性炔丙基胺可以高收率和高对映选择性地得到相应的炔丙基胺。 。
