Catalyst- and solvent-free, pot, atom and step economic synthesis of tetrahydroquinazolines by an aza-Diels–Alder reaction strategy

Abstract

A pot, atom and step economic (PASE) synthesis of tetrahydroquinazolines has been achieved via a microwave-assisted four-component catalyst- and solvent-free aza-Diels–Alder reaction strategy. The key step of the methodology is the in situ generation of both the diene and the dienophile and their subsequent reaction to give the desired product.
