Synthesis of a series of tricyclic quinazolinones have been accomplished starting from anthranilamide and 1,3-cyclic dione promoted by TsOH·H2O The protocol presented herein based on retro-Dieckmann type reaction, leading to incorporation of dione as an acyclic unit into the product. Simple reaction conditions, broad scope, excellent yields are the advantages of this protocol. Further, this methodology
从蒽醌和由TsOH·H 2 O促进的1,3-环二酮开始,已经完成了一系列三环喹唑啉酮的合成。本文提出的方案基于Retro-Dieckmann型反应,导致将二酮作为无环单元掺入产品。简单的反应条件,广泛的范围,优异的收率是该方案的优点。此外,该方法学扩展至吡啶并嘧啶酮和苯并咪唑并吡啶的合成。
