Herein, we report a modular synthetic route to linear and branched homoallylic amines that operates through a sequential one-pot Lewis base/transition-metal catalyzed allylic alkylation/Hofmann rearrangement strategy. This protocol is operationally trivial, proceeds from simple and easily prepared substrates and catalysts, and enables all aspects of regio- and stereoselectivity to be controlled through
在本文中,我们报告了通过顺序的一锅路易斯碱/过渡金属催化的烯丙基烷基化/霍夫曼重排策略操作的线性和支链均烯丙基胺的模块化合成路线。该方案操作简单,从简单容易制备的底物和催化剂开始,并通过保守的实验方案控制区域选择性和立体选择性的所有方面。总的来说,获得高水平的对映体,区域和非对映体选择性,以及获得正交保护的或游离的胺的能力,使得这成为制备有用的对映体富集的均烯丙基胺的直接有效的方法。我们还证明了该产品在药物合成中的实用性。
