Recent advances in 4-hydroxycoumarin chemistry. Part 2: Scaffolds for heterocycle molecular diversity
Abstract
The present paper aims to review the synthetic applicability of 4-hydroxycoumarin in heterocyclic synthesis during the period from 1996 up to now. This compound can be used as building blocks for five, six, and seven-membered heterocycles as well as fused rings. Keywords: 4-Hydroxycoumarin, Annelated heterocycles, Multicomponent reactions, Green chemistry
