A mild and convenient synthesis of quinoxalines via cyclization–oxidation process using DABCO as catalyst
摘要:
An efficient and general method has been described for the synthesis of quinoxalines by the reaction of 1,2-diamines with phenacyl bromides in the presence of DABCO. The method is suitable for the preparation of functionalized quinoxalines. (C) 2010 Elsevier Ltd. All rights reserved.
