Graphical Abstract:


A simple and highly efficient approach for the synthesis of γ-Benzopyranones and 3,4- Dihydropyrimidin-2(1H)-ones/thiones using ammonium acetate as a promoter under thermal as well as microwave irradiation using solvent-free conditions has been demonstrated.

Keywords: γ, 3, 4-dihydropyrimidin-2(1H)-ones/thiones, ammonium acetate, solventfree synthesis, promoter.
