Reported herein is a modular, NiH-catalyzed system capable of proximal-selective hydroamination of unactivated alkenes with diverse amine sources. The key to the successful implementation of this approach is the promotion of NiH insertion into even highly substituted olefins via coordination of the bidentate directing group to the nickel complex. A wide range of primary and secondary amines can be installed in both internal and terminal unactivated alkenes with excellent regiocontrol under the optimized reaction conditions. This protocol is flexible and general for the preparation of a variety of valuable β- and γ-amino acid building blocks that would otherwise be difficult to synthesize. The utility of this transformation was further demonstrated by the site-selective late-stage modification of complex and medicinally relevant molecules. Combined experimental and computational studies illuminate the detailed reaction mechanism.

NiH 催化未活化烯烃的近端选择性加氢胺化

本文报道了一种模块化的 NiH 催化系统，该系统能够对具有不同胺源的未活化烯烃进行近端选择性加氢胺化。这种方法成功实施的关键是通过双齿导向基团与镍配合物的配位促进 NiH 插入甚至高度取代的烯烃中。在优化的反应条件下，可以将各种伯胺和仲胺安装在内部和末端未活化的烯烃中，并具有出色的区域控制。该协议灵活且通用，可用于制备各种有价值的 β- 和 γ- 氨基酸构建块，否则这些构建块将难以合成。复杂和医学相关分子的位点选择性后期修饰进一步证明了这种转化的效用。
