Abstract


Dicalcium phosphate dihydrate (DCPD) was used as a green and reusable catalyst in order to synthesized two important categories of heterocycles, 3,4-dihydropyrimidin-2-ones and 3,4-dihydropyrimidin-2-thiones. The advantages of our method are as follow: short reaction times, green process, reduced environmental hazards and high isolated yield of products.

Keywords
