Solvent Free Conditions

An efficient and facile one pot synthesis of 3,4-dihydropyrimidinones (Belinelli compound) from furfural, acetylacetone and urea under solvent free conditions was performed, resulted in promising yield. These compounds reacted with benzaldehyde and furfural to give the corresponding chalcones. Chalcones are used to synthesize several derivatives like pyrazolines isoxazoles and pyrimidines having different heterocyclic ring systems. Keywords: Belinelli compounds; Chalcone; Pyrazolines isoxazoles; Pyrimidines
