An asymmetric Lewis acid-mediated [2,3]-sigmatropic rearrangement of allylic amines has been developed, affording the corresponding homoallylic amines in good yield and excellent enantioselectivities. The rearrangement proceeds by complexation of the chiral Lewis acid to the amine followed by deprotonation and rearrangement.
不对称路易斯酸介导的烯丙基胺的 [2,3]-σ 重排已被开发,以良好的产率和优异的对映选择性提供相应的高烯丙基胺。重排通过手性路易斯酸与胺络合,然后去质子化和重排进行。
