摘要：

A novel way of synthesizing quinoxalines has been developed that involves condensation and C-N bond formation in a copper-catalyzed, one-pot, three-component reaction. The reaction was optimized when 2-iodoanilines (1.0 equiv), arylacetaldehydes (2.0 equiv), sodium azide (1.2 equiv), CuI (10mol%), DMEDA (10mol%), and K2CO3 (1.0 equiv) were reacted in DMSO at 80 degrees C for 20hours. This approach was used to directly synthesize a variety of quinoxalines in moderate to good yields.
