The direct N-alkylation of 2-aminoimidazoles to give the corresponding 2-(N-alkylamino)imidazoles was accomplished using alcohols as alkylating agents in the presence of a [Cp*IrCl2]2/K2CO3 system. The iridium-catalyzed regioselective reaction is simple, efficient, general, and environmentally benign.
在 [Cp*IrCl2]2/K2CO3 系统存在下,使用醇作为烷基化剂,完成 2-氨基咪唑的直接 N-烷基化以得到相应的 2-(N-烷基氨基)咪唑。铱催化的区域选择性反应简单、高效、通用且对环境无害。
