benzo[c]-2,7-naphthyridine have been prepared in fair to excellent yields and in one step by the Pd(0)-catalyzed cross-coupling of pyridine methylstannanes with ortho bromoacetanilides. The coupling is greatly promoted by the addition of copper(II)oxide.
苯并[c] -2,7-萘啶的衍生物已经以相当高的收率制备,并且一步法通过吡啶(甲基)吡啶(Pd(0))催化的吡啶甲基锡烷与邻溴乙酰苯胺的交叉偶联而制备。通过加入氧化铜(II)极大地促进了偶联。
