An efficient and simple method for the synthesis of 3‐carbamoylated quinoxalin‐2(1H)‐ones base on copper‐catalyzed directcarbamoylation of quinoxalin‐2(1H)‐ones at C3 position has been reported, This process provides a series of 3‐carbamoylquinoxalin‐2(1H)‐one derivatives in moderate to good yields under mild conditions with good functional group tolerance. This work provides a novel and efficient
