Abstract

An efficient synthesis of novel 4-(2-phenyl-1,2,3-triazol-4-yl)-3,4- dihydropyrimidin2(1H)-(thio)ones from 1,3-dicarbonyl compounds, 2-phenyl-1,2,3-triazole-4carbaldehyde and urea or thiourea under ultrasound irradiation and using samarium perchlorate as catalyst is described. Compared with conventional methods, the main advantages of the present methodology are milder conditions, shorter reaction times and higher yields. Copyright © 2010 by the authors.
