## Abstract An efficient solvent‐free method for the synthesis of various 3,4‐dihydropyrimidin‐2(1__H__)‐ones using TiO~2~ as a recyclable heterogeneous catalyst is described. Compared to known methods, satisfactory results are obtained with excellent yields, short reaction times, and simplicity in
## Abstract A simple, efficient and convenient one‐pot synthesis of 2,3‐dihydroquinazolin‐4(1__H__)‐one derivatives under solvent‐free and catalyst‐free conditions by the reaction of aromatic aldehydes, isatoic anhydride, and ammonium acetate was reported. The advantages of this protocol include sh
