چکیده
|
An effective synthesis of 3,4-dihydropyrimidin-2(1h)-one derivatives using ionic liquid 1-n-butyl-3-methylimmidazolium hexafluorophosphate ([bmim]pf 6) as the catalyst from aldehydes,1,3-dicarbonyl compounds and urea (thiourea) under microwave irradiation is described. this new method has the advantage of high yields (80-95% for aromatic aldehydes) and short reaction time (3-5 min).
