在无溶剂反应条件下,萘酚和互变异构酚衍生物的羟基已被O-,S-,N-和C中心的亲核试剂取代。产生的产品良率极佳。与其他布朗斯台德酸相比,对甲苯磺酸显示出最佳的催化活性。实验观察表明该反应通过萘酚的酮互变异构体的中间体进行。亲核加成到羰基上,然后除去水,得到所需产物。本方法提供了对取代的萘[2,1- b ]呋喃衍生物的访问。使用N生成的产品以中心为中心的亲核试剂可以进一步转化为重要种类的有机分子,例如苯并咔唑和咪唑衍生物。

One‐pot synthesis: An efficient amino‐directed one‐pot synthesis of NHcarbazoles from unprotected 2‐aminobiaryl compounds is reported. The free amino unit acts as both a directing group for ortho CHactivation and a functional group for construction of an N‐heterocyclic ring (see scheme).
