Dodecylphosphonic acid is a solid Bronsted acid that catalyzesefficiently the preparation of dihydropyrimidinones by Biginelli condensation undersolvent-freeconditions. This protocol offers several advantages including high yields, short reaction times, easy work-up, and use of cheap, relatively moderate acidic and safe catalyst.

In this investigation, a practical green chemistry procedure for synthesis of octahydroqinazolinones and thiones derivatives via condensation of aldehyde, 1,3‐cyclohexanedione/dimedone and urea or thiourea catalyzed by magnetic roomtemperature dicationic liquid undersolventfreeconditions is described. The catalyst was studied by UV spectroscopy, vibrating sample magnetometer, and thermogravimetric
1-Methylimidazolium hydrogen sulfate/chlorotrimethylsilane: An effective catalytic system for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and hydroquinazoline-2,5-diones
Brønsted acidic ionicliquid, 1-methylimidazolium hydrogen sulfate, in the presence of catalytic amount of chlorotrimethylsilane has been used as an efficient and reusablecatalyst for the one-potsynthesis of 3,4-dihydropyrimidin-2(1H)-ones and hydroquinazoline-2,5-diones under thermal and solvent-free conditions. High yields of the products were obtained in a few minutes by using this new catalysis
