chiral dirhodium-carboxylates-catalyzed asymmetric nitrene/alkyne metathesis (NAM) cascade reaction of alkyne-tethered sulfamates has been developed, which provides a general access to the synthesis of tricyclic N-heterocycles in good yields and excellent enantioselectivity. The chiral dirhodium catalyst not only promotes the nitrene/alkyne metathesis (NAM) to generate the key α-imino metal carbene intermediate
已开发了由炔烃系束缚的氨基磺酸盐的手性羧酸二铜鎓催化的不对称腈/炔烃复分解(NAM)级联反应,为合成三环N-杂环化合物提供了普遍途径,收率高且对映选择性优异。手性dirhodium催化剂不仅促进了氮烯/炔烃复分解(NAM)生成关键的α-亚氨基金属卡宾中间体,而且还导致了在氧鎓叶立德物种的终止[2,3]-σ重排中观察到的不对称诱导。
