The reaction of N-arylamidines (III) with appropriate 2-alkynoic ester gives 2,6-disubstituted 3-aryl-4(3H)-pyrimidones (IV) in one step except in the reaction of N-(2-trifluoromethylphenyl/biphenyl)-S-methylisothiourea with ethyl propiolate, where the required pyrimidones (IVa17/IVa20) along with the adduct (Va/Vb) have been isolated; these adducts on cyclisation yield the corresponding pyrimidinones (IVa17/IVa20). 2,3,6-Triphenyl-4(3H)-pyrimidone (IVh1) on treatment with P2S5 furnishes the corresponding thione (VI).Some of these compounds have shown significant central muscle relaxant, hypnotic, anticonvulsant, CNS depressant, antiinflammatory and diuretic activities.
