A new procedure for the synthesis of 5-unsubstituted 3,4- dihydropyrimidin-2(1H)-ones is described. Two plausible mechanisms for the key chemical transformation are advanced.

A new and efficient method has been developed for the quantitative transformation of chalcones to pyrimidine frame work vSa solid support catalysis, Silica supported sulphuric acid (SSA) efficiently catalyzed the reaction of α-β-unsaturated earbonyl, chalcones (140) with urea to afford substituted pyriniidin-2(1H)-ones (11-20) hi good to excellent yield. The interesting behaviour of SSA lies in the thct that it can be re-used after simple washing with chloroform thereby rendering this procedure more economical, The chemical structures were confirmed by analytical data as well as spectroscopic means.
