posted on 2018-03-09, 15:25 authored by Jing Zi, Da-Wei Gu, Yan Zhang, Zhe-Yao Hu, Xing-Quan Zhang, Xun-Xiang GuoThe synthesis of N-heterocycles of quinoxalines has been developed by an efficient protocol of one-pot annulation of alkynes with o-phenylenediamines. A variety of quinoxalines were prepared in good to high yields in the presence of catalytic amount of iodine as a catalyst.
