The highly enantioselective copper-catalyzed propargylic amination of propargylic esters with amine hydrochloride salts has been realized for the first time using copper salts with chiral N,N,P-ligands. This method features a broad substrate scope and wide functional group tolerance, generating propargylic amines in good to excellent yields with high enantioselectivities (up to 99% ee). The utility
首次使用具有手性N,N,P配体的铜盐实现了炔丙基酯与胺盐酸盐的高度对映选择性的铜催化炔丙基胺化。该方法具有广泛的底物范围和宽泛的官能团耐受性,可生成具有高对映选择性(高达99%ee)的良至优收率的炔丙基胺。该方法的实用性通过市售药品的后期功能化得以证明。
