Vicinal tricarbonyl intermediates are directly synthesized from β-dicarbonyls with the aid of Cu(II) salts and air, and they are further condensed with phenylene diamine to produce a range of quinoxalines in moderate to good yields in one-pot reaction.
邻位三羰基中间体是借助Cu(II)盐和空气直接由β-二羰基合成的,然后进一步与亚苯基二胺进行缩合反应,以一锅反应以中等到良好的产率生产一系列
喹喔啉。
