A copper-catalyzed electrophilic, umpolung amination strategy for the direct C-H amination of polyfluoroarenes and 1,3-azoles has been developed. The copper-based amination reaction is robust and can be easily scaled up on a gram scale. Its application to an annulative electrophilic amination of o-alkynylphenols and -anilines for the synthesis of 3-aminobenzofurans and -indoles is also described.
开发了一种铜催化的亲电性乌姆堡胺化策略,用于直接实现多氟芳烃和1,3-唑的C-H胺化。基于铜的胺化反应具有鲁棒性,可以轻松地在克规模上扩大规模。还描述了其在邻炔基苯酚和苯胺的累积亲电胺化反应中的应用,用于合成3-氨基苯并呋喃和吲哚。
