Enamines served as carbon-nucleophiles for the first time in the Cu-catalyzed asymmetric propargylic substitution reaction of propargylic acetates, providing corresponding chiral β-ethynyl-substituted ketones in high yields and in good to high enantioselectivity.
烯胺首次在乙酸丙炔乙酸酯的铜催化的不对称炔丙基取代反应中用作碳亲核试剂,以高收率和良好至高对映选择性提供相应的手性β-乙炔基取代的酮。
