• One-pot synthesis of 2-substituted quinoxalines using K10-montmorillonite as heterogeneous catalyst
  作者：Mariappan Jeganathan、Amarajothi Dhakshinamoorthy、Kasi Pitchumani

  DOI：10.1016/j.tetlet.2014.01.087

  日期：2014.2

  An efficient one-pot synthesis of 2-substituted quinoxalines from 1,2-diamines and phenacyl bromides is developed using K10-montmorillonite (K10 clay) as a catalyst at 50 degrees C in acetonitrile medium. This method offers an easy route for the synthesis of substituted quinoxalines in high yields. A plausible mechanism is proposed in which quinoxalines are formed via dehydration-dehydrohalogenationcyclization sequence. Further, the K10 clay catalyst is recovered by simple filtration and reused six times without any loss in its catalytic activity. (C) 2014 Elsevier Ltd. All rights reserved.
