Dihydropyrimidinones and their derivatives were synthesised in high yields by a one-pot threecomponent Biginelli condensation in th epresence of catalytic amounts of room temperature ionic liquids such as 1-n-Butyl- 3-methylimidazolium tetrafluoroborate (BMImBF4) and hexafluorophosphorate (BMImPF6) under neurtral and solvent-free conditions. The one-pot Biginelli condensation has such advantages as high-yields, short reaction time, and simple procedure.
