چکیده
|
Montmorillonite modified was used as an efficient environmental friendly catalyst for synthesis of 3,4 dihydropyrimidine-2(1h) ones under one-pot-three-component reaction. the preparation was performed with an aldehyde, 1,3-dicarbonyl compounds, urea or thiourea under solvent-free conditions. in comparison with the other methods of biginelli reaction, this new method has short reaction time, inexpensive catalyst and in addition excellent yields were obtained
