Recent Advances on Diversity Oriented Heterocycle Synthesis of Fused Quinazolinones

Abstract

During the last decade quinazolinones derivatives have been shown to be useful building blocks for the synthesis of a variety of functionalized polynuclear heterocyclic systems. This review presents the recent systematic and comprehensive literature survey of fused quinazolinones synthesis. These fused heterocycles are classified according to the ring volume starting from three membered up to seven membered cycles and divided according to the number of heteroatoms and type or position of these heteroatoms.
