چکیده
|
In this study, a green approach is reported for efficient and rapid synthesis of biologically active substituted 3,4-dihydropyrimidin-2(1h)-one(thione) derivatives using nano sbcl5.sio2 as a heterogeneous catalyst under solvent-free conditions. the catalyst is characterized by ft-ir, xrd, sem, tem and tg-dtg analysis. compared to the classical reactions, this method consistently has the advantages of excellent yields, simple operation, short reaction time, eco-friendly and avoidance of the use of organic solvents.
