KaradeA clean and simple synthesis of tetrahydrobenzo[b]pyrans and pyrano[2,3- d]pyrimidinederivatives was accomplished in good to excellent yields via one-pot, three component condensation of cyclic 1,3-dicarbonyl compounds, aromatic aldehydes and malonitrile in ethanol solvent catalyzed by montmorilloniteK- 10.
