One-step approach for the synthesis of functionalized quinoxalines mediated by T3P®–DMSO or T3P® via a tandem oxidation–condensation or condensation reaction

Abstract

An easy and efficient propylphosphonic anhydride (T3P®)–DMSO or T3P® mediated oxidation–condensation or condensation reaction for the synthesis of quinoxalines derived from the interaction of different arrays of condensing partners with ortho-phenylene diamines (o-PDs) under simple and mild reaction conditions in one step has been reported for the first time.
