Microwave-assisted three-component condensation on montmorillonite K10: Solvent-free synthesis of furopyrimidines, furocoumarins, and furopyranones

Rapid and efficient one-pot three-component condensation synthesis of furopyrimidines, furocoumarins, and furopyranones are described which occur in the presence of montmorillonite K10 using microwave irradiation under solvent-free conditions.
