烷基胺类化合物是重要的有机分子, 对其不同位点的碳氢键进行精准转化是当前有机合成化学的研究热点之一. 氢原子迁移(HAT)作为一种温和可控的碳氢键活化策略, 近些年来受到了极高的关注并被广泛用于胺类分子的选择性碳氢键转化. 通过分子间或分子内HAT过程可以精准导向攫取胺类分子中特定位点的氢原子并实现后续转化, 为复杂胺类功能分子的高效构筑提供了全新的合成思路. 总结了基于上述策略的胺类分子碳氢键选择性官能团化反应进展, 对其中的区域、化学和立体选择性调控机制以及反应机理进行评述, 分析存在的局限性以及展望未来研究方向.

Aliphatic amines are pivotal organic molecules, and therefore the precise C—H transformation of amines at distinct sites has long been a research focus in organic synthesis. Hydrogen atom transfer (HAT), recognized as a mild and controllable strategy for C—H activation, has attracted considerable attention in recent years and is extensively employed for the selective C—H transformation of amine molecules. By leveraging intermolecular or intramolecular HAT processes, it becomes feasible to precisely abstract C—H bonds at specific sites within amine molecules and facilitate subsequent transformations, providing novel synthetic pathways for the efficient construction of complex functional amine molecules. The recent advances in the selective functionalization of C—H bonds of amine molecules using the aforementioned strategy are comprehensively summarized. A review is conducted on the regio-, chemo-, and stereoselective regulatory mechanisms, as well as the reaction mechanisms involved. In addition, the limitation in this research field is analyzed and the outlook of this area is also prospected.
