A new catalytic strategy from commercial nitriles to high enantioselective α-tertiary primary amines in up to 90 % yield and 95 % enantiomeric excess was developed. This approach goes through twice addition processes in one pot. Specifically, organolithium reagents were added to nitriles to form the imine intermediates in situ which were further transformed by a catalytic asymmetric addition of Cu-allyl
开发了一种从商业腈到高对映选择性 α-叔伯胺的新催化策略,收率高达 90%,对映体过量达 95%。这种方法在一个锅中经过两次添加过程。具体而言,将有机锂试剂添加到腈中以原位形成亚胺中间体,通过催化不对称加成 Cu-烯丙基进一步转化亚胺中间体,得到 α-叔均烯丙基 NH 2 -胺。
