The stereoselective allylation of acyclic chiral α-amino aldimines affording vicinal diamines, mediated by various Lewis acids (TiCl4, SnCl4, MgBr2·OEt2, BF3·OEt2, ZnCl2), is described. The TiCl4-mediated allylation of an α-N-Boc aldimine afforded the allylation product with syn-selectivity, which in turn was used for the synthesis of an intermediate of an oseltamivir derivative.
描述了由各种路易斯酸(TiCl 4,SnCl 4,MgBr 2 ·OEt 2,BF 3 ·OEt 2,ZnCl 2)介导的提供邻位二胺的无环手性α-氨基醛亚胺的立体选择性烯丙基化。TiCl 4介导的α- N- BocAldimine的烯丙基化提供了具有顺选择性的烯丙基化产物,该产物又用于合成奥司他韦衍生物的中间体。
