The efficient one-pot condensation of aldehyde, dimedone, and phthalhydrazide has been achieved in the presence of a catalytic amount of phospho sulfonic acid as a novel environmentally benign heterogeneous solid acid under solvent-free conditions. A diversified 2H-indazolo[1,2-b]phthalazinetrione derivatives were prepared in good to excellent yields in short time. The economical factors (time, cost, waste etc.) for this three-component reaction hold promise for the future of organic synthesis.

Abstract: Catalyzed with SCMNPs@CA-EA-SO3H, as a green and heterogeneous solid acid catalyst, 3,4-dihydropyrimidin-2(1H)-one and octahydroquinazolinone derivatives were obtained in high-to-excellent yields and in short reaction times via the one-pot multi-component condensation of ethyl acetoacetate or dimedone, urea, and aldehyde compounds under solvent-free conditions. More importantly, the green catalytic system could be easily collected from the reaction solution utilizing an external magnet and reused for five runs with a negligible decrease in yields and reaction rate.
