Abstract

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.
