A mechanistic insight into the acid catalyzed, one-pot synthesis of isoindole-fused quinazolin 4-ones

Abstract

One-pot synthesis of isoindole fused quinazolin 4-ones via intramolecular 1,3 hydride transfer in the presence of acid catalyst has been described. Substrate scope and mechanistic insights were investigated. Substituents on the amide side have a negligible influence on the key step and therefore the method have wide scope for accessing various bicyclic core structure.
