An effective one-pot synthesis of dihydropyrimidinonoes in solvent free conditions using CuCl2 as an inexpensive and readily available reagent through Biginelli condensation reaction of aldehyde derivatives, 1,3-dicarbonyl compounds and urea is described. Excellent yields, short reaction times for formation of the products and simple work-up are attractive features of this green protocol.

In the present paper, synthesis of new series of 1,3,4oxadiazole derivatives incorporating substituted dihydropyrimidinone and chloroquinoline moieties 4(a-j) has been reported. All the synthesized compounds were characterized by FTIR, 1 H NMR and Mass spectroscopy. The compounds were screened for their in vivo anti-inflammatory activity by the carrageenan induced rat paw edema method and in vi...

The purpose of this study was to synthesize substituted 3,4-dihydropyrimidin-2(1H)ones (DHP) and to evaluate them for their antibacterial and antifungal activities. These compounds were synthesized by cyclocondensation reaction between substituted aromatic aldehyde i.e.,p-anisaldehyde, active methylene compounds (ethyl acetoacetate/acetylacetone), urea in the presence of CuCl2.2H2O and few drop...
