The efficient electrochemically promoted [3 + 2] annulation of imidazo[1,2-a]pyridines with alkynes using traceless electrons as green reagents has been developed, leading to the synthesis of a large class of polycyclic heteroaromatics in good yields with a broad substrate scope under mild and green conditions. The scaled-up experiment, follow-up procedures, and potential biological applications show
使用无痕电子作为绿色试剂,开发了咪唑并[1,2- a ]吡啶与炔烃的高效电化学促进[3 + 2]成环反应,从而可以在广泛的底物下以良好的产率合成一大类多环杂芳烃在温和和绿色条件下的范围。放大实验、后续程序和潜在的生物学应用表明了电化学方法的实用性和可行性。
