Abstract The acidic ionic liquids were new catalysts for the one-pot Biginelli reaction coupling of aldehyde, 1,3-dicarbonyl compound, and urea to afford the corresponding dihydropyrimidinones in good yields under solvent-freeconditions. The catalysts could be recycled and reused five times without a noticeable decrease in catalytic activity.

Dihydropyrimidones 1–37 were synthesized via a ‘one-pot’ three component reaction according to well-known Biginelli reaction by utilizing Cu(NO3)2·3H2O as catalyst, and screened for their in vitro β-glucuronidase inhibitory activity. It is worth mentioning that amongst the active molecules, compounds 8 (IC50 = 28.16 ± .056 μM), 9 (IC50 = 18.16 ± 0.41 μM), 10 (IC50 = 22.14 ± 0.43 μM), 13 (IC50 = 34.16 ± 0
