Abstract
Abstract 3,4-Dihydropyrimidin-2(1 H )-ones were synthesised in high yields by one-pot three-component Biginelli condensation in the presence of room temperature ionic liquids such as 1- n -butyl-3-methylimidazolium tetrafluoroborate (BMImBF 4 ) or hexafluorophosphorate (BMImPF 6 ) as catalysts under solvent-free and neutral conditions.
