摘要：

The synthesis of benzoxazoles and benzimidazoles is accomplished by treating N,O-diacylated 2-aminophenols or N,N'-diacylated 1,2-phenylenediamines with p-toluenesulfonic acid under reflux in xylenes or toluene. These reactions are operationally simple and proceed in excellent yield. Copyright (C) 1996 Elsevier Science Ltd
