A new combination of reagent (ZnCl2/TBAB) system has been developed for the preparation of dihydropyrimidinones by using aldehyde, acetoacetic ester and urea or thiourea. These improved reaction condition allow the preparation of a wide variety of substituted dihydropyrimidinones in high yields and purity under mild reaction conditions. Some of the dihydropyrimidinones were showed moderate in vitro

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
