Green synthesis and structural characterization of novel N1-substituted 3,4-dihydropyrimidin-2(1H)-ones

Novel N1-substituted 3,4-dihydropyrimidin-2(1H)-one derivatives were synthesized through Biginelli condensation of aromatic aldehydes, β-ketoesters, and monosubstituted (thio)ureas in the presence of copper methanesulfonate at 90°C under solvent-free conditions. The screening of the catalysts showed...
