Abstract :
The substituted 3,4-dihydropyrimidin-2(1H)-ones and their thione analogues have been prepared Via Biginelli condensation using aldehyde, 1,3-dicarbonyl compound and urea or thiourea under the catalystof sulphamic acid (H2NSO3H). The method is simple, cost-effective, and gives good yields in a shorter reactiontime.
