In this work, we report a simple, efficient and green protocol for the synthesis of dihydropyrimidinones/thiones (products of Biginelli reaction) by the use of white marble as an effective heterogeneous catalyst. Short reaction times, high product yields, simple processing procedure and reusability of the catalyst are the superior characteristics of this protocol.

Keywords: Biginelli reaction; 4-dihydropyrimidin-2(1H)-ones/thiones; white marble; green catalyst
