摘要

我们报告了一个铜催化烯烃的直接烯丙基胺化，使用现成的邻苯并羟胺作为烷基胺前体和内部氧化剂。一系列的伯烷基胺和仲烷基胺可以安装在不同取代的烯烃上，以快速构建n -烷基烯丙胺。机理研究表明，该反应的初始亲电胺化反应具有反马尔可夫尼科夫选择性，随后是区域选择性氧化消除，以提供双键转位。在亲电胺化步骤中，使用强Brønsted酸对于生成关键的胺基阳离子（ARC）物种至关重要。

Copper-Catalyzed Allylic Amination of Alkenes Using O-Acylhydroxylamines: A Direct Entry to Diverse N-Alkyl Allylamines

We report a copper-catalyzed direct allylic amination of alkenes using readily available O-benzyolhydroxylamines as the alkylamine precursors and internal oxidant. A range of primary and secondary alkylamines can be installed onto diversely substituted alkenes for the rapid construction of N-alkyl allylamines. Mechanistic studies support that the reaction engages an initial electrophilic amination to alkenes with anti-Markovnikov selectivity and subsequently a regioselective oxidative elimination to furnish the double bond transposition. In the electrophilic amination step, the use of strong Brønsted acid is critical for generating the key aminium radical cation (ARC) species.
