The application in alkylation reactions of an acyclic chiral auxiliary is described. The synthesis is straightforward from a chiral primary amine and a double acylation. A characteristic of this auxiliary is its modular design formed by an achiral part (acyl) and a chiral component (primary amine) so it can be tuned for different reactions without difficulty. The alkylation proceeds with excellent
描述了无环手性助剂在烷基化反应中的应用。从手性伯胺和双酰化反应可以直接合成。这种助剂的一个特点是其由非手性部分(酰基)和手性组分(伯胺)形成的模块化设计,因此可以轻松地针对不同的反应进行调整。烷基化以优异的非对映选择性进行,因为烯醇盐的构象柔韧性受到螯合物和1,3-烯丙基烯丙基菌株的形成的限制。
