摘要
研究了一种碱性条件下由邻氨基芳香腈1与醛2一锅合成4(3H)-喹唑啉酮3的新方法.反应经由亲核加成、分子内的Pinner关环、Dimroth重排和氧化脱氢串联转化而成.产物结构经1H NMR,13C NMR,IR和元素分析确证.
A series of 4(3H)-quinazolinones 3 were obtained from the one-pot synthesis of available substituted aromatic o-aminonitriles 1 with aldehydes 2 in the present of base.This tandem transformation was included in addition,intramolecular Pinner reaction,Dimroth rearrangement and oxidative dehydrogenation.The structures of products were characterized by 1H NMR,13C NMR,IR spectra and elemental analysis.
