Microwave-assisted synthesis of dihydropyrimidin-2(1H)-ones using graphite supported lanthanum chloride as a mild and efficient catalyst.

Hojatollah Khabazzadeh1, Kazem Saidi, Hassan Sheibani.   

Abstract

Graphite supported lanthanum chloride efficiently catalyzes the three-component coupling of beta-ketoesters, aldehydes and urea/thiourea to afford corresponding dihydropyrimidinones in good yields under microwave irradiation.
