An expedient microwave-assisted, solvent-free, solid-supported synthesis of pyrrolo[2,3- d]pyrimidine-pyrano[5,6- c]coumarin/[6,5- c]chromone derivatives by intramolecular hetero Diels–Alder reaction

Abstract

A rapid synthesis of pyrrolo[2,3- d]pyrimidine annulated pyrano[5,6- c]coumarin/[6,5- c]chromone derivatives has been accomplished in good yields via an intramolecular domino hetero Diels–Alder reaction using microwave irradiation under solvent-free, solid-supported conditions.
