An efficient, novel procedure for the synthesis of new imidazole derivatives from alpha-azido ketones is described. This reaction proceeds via dimerization of aryl glyoxal imino generated from alpha-azido ketones in the presence of potassium ethylxanthate as a catalyst. A possible mechanism for the entire sequence is proposed. (c) 2013 Elsevier Ltd. All rights reserved.
