highly stereoselective synthesis of hitherto less accessible chiral α‐tertiary amines with multiple structurally similar linear carbon chains was achieved through chiral auxiliary mediated addition of organolithium reagents to the geometrically well‐controlled alkynyl Z‐ketimines. This stereoselective nucleophilic addition offers a general approach to the asymmetric synthesis of nitrogen‐containing
通过手性辅助介导将有机锂试剂添加到几何形状良好控制的炔基Z-酮亚胺中,可以实现迄今为止难以获得的具有多个结构相似的线性碳链的手性α-叔胺的高度立体选择性合成。这种立体选择性亲核加成为含氮手性材料的不对称合成提供了一种通用方法。
