摘要
A series of new quinoxalines has been obtained from a one pot, three-component reaction of (2-arylsulfanyl-3-aryl-2oxiranyl)(aryl)methanones with o-phenylenediamine in the presence of a catalytic amount of acetic acid. This reaction presumably involves a tandem oxirane aminolysis-cyclisation-elimination-air oxidation-condensation sequence. (c) 2007 Published by Elsevier Ltd.
