Cu(II)-catalyzed synthesis of quinoxalines from o-phenylenediamines and nitroolefins
摘要:
An easy and efficient copper-catalyzed reaction for the synthesis of quinoxalines from o-phenylenediamines and nitroolefins is developed. This reaction could proceed well without additional base and be applied to various available substrates with a one-step synthetic procedure in moderate to good yields. (c) 2012 Elsevier Ltd.
