A simple method for the synthesis of quinazolines was developed by exploiting the “tert-amino effect.” A catalytic amount of Brønsted acid (TsOH·H2O) worked as an effective activator for the concise construction of a quinazoline framework from o-formylaniline and amine.
利用 "叔氨基效应",我们开发出了一种合成喹唑啉类化合物的简单方法。催化量的布氏硬度酸(TsOH-H2O)是一种有效的活化剂,可使邻甲酰苯胺和胺简洁地构建喹唑啉框架。
