Biginelli reaction entails acid-catalyzed one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) with simply-accessible initial substances, specifically, aldehyde, urea, and active methylene compound. DHPMs have stimulated a resurgence of attention in the previous two decades because of their broad-ranging pharmacological actions and the existence of varied all-natural products. Currently, green methods to asymmetric Biginelli reaction have been researched for anti-inflammatory DHPMs. In materials chemistry, DHPMs are increasingly decision applications in the creation of materials like polymers, adhesives, fabric dyes, etc. In light of the simplicity by which the Biginelli reaction is conducted, numerous interesting prospects expect its exploitation in variety fields. CoFe2O4?SiO2-NH2-CoII is herein turned out to be an effective catalyst at a three-component Biginelli reaction. The yield of the corresponding DHPMs was rather large (20 cases; average 92 percent). Finally, we herein suggest a procedure that shows lots of advantages and benefits such as the whole lack of solvents, mild reaction conditions, comparatively short reaction times. Also, CoFe2O4?SiO2-NH2-CoII NPs catalyst has been readily recovered from the reaction combination and reused, without the decrease of catalytic action.
