Different alkalinemetal (II) sulfates were used as catalysts for the N,N′-dimethylsubstituted as well as unsubstituted 4-aryl-3,4-dihydropyrimidones (thiones) and their correspondingbis-analogues in aqueousmedium. Among the various salts, MgSO4·7H2O (Epsom salt) proved to be the best catalyst giving the desired products in good to excellent yields. This catalyst enables the construction of a series

By combining the structural features of dihydropyrimidinone and 1,2,3-triazole heterocycles, novel hybrid compounds were synthesized using a simple and convenient method. A series of novel mono and bis 1,2,3-triazole was synthesized via copper-catalyzed Huisgen azide-alkyne cycloadditions (CuAAC) under microwave irradiation. The newly synthesized compounds were evaluated for their antiviral activity against varicella-zoster virus (VZV). Compounds 6aa, lab, 6ba and 6da showed valuable antiviral activities, with EC50 values ranging from 3.6 to 11.3 mu M against TK+ and TK- VZV and without measurable cell-growth inhibition.
