A green method to synthesize cinnolines by 6π electrocyclic reaction with alkenyl amines and TBN has been developed. TBN plays a dual role both as the nitrogen atom source and oxidant in this procedure. Relevant mechanism experiments reveal the reaction proceeds through electrocyclic reaction and with diazo hydroxide as a key intermediate.
已开发出一种绿色方法,可通过与烯基胺和TBN的6π环化反应合成辛啉。TBN在此过程中既充当氮原子源又充当氧化剂。相关的机理实验表明,反应是通过环化反应进行的,并以重氮氢氧化物为关键中间体。
