4‐Dihydropyrimidinone and derivatives were synthesized by the one‐pot, three‐component Biginelli condensation of an aldehyde, β‐dicarbonyl compound and urea. Synthesis was carried out in aqueous sodium hydroxide using Aliquat‐336 as a phasetransfer agent. Compared to the classical Biginelli reaction conditions, this new method cousistently has the advantage of excellent yields and short reaction time

An efficient magnetically recyclable bimetallic catalyst by anchoring copper and manganese complexes on the Fe3O4 NPs was prepared and named as Fe3O4@Cu-Mn. It was founded as a powerful catalyst for the domino one-pot oxidative benzimidazole and Biginelli reactions from benzyl alcohols as a green protocol in the presence of air, under solvent-free and mild conditions. Fe3O4@Cu-Mn NPs were well characterized
