ZrCl4-catalyzed one-pot multi-component synthesis of hexahydropyrano pyrimidinone derivatives

Özet

In this study, zirconium tetrachloride is used as a highly efficient catalyst for the one-pot three component reaction of 3,4-dihydro(2H)-pyran, urea and benzaldehyde in ethanol, producing corresponding hexahydropyrano pyrimidinone derivatives in good yields, with excellent diastereoselectivity. This method has various benefits such as easy availability of starting materials, lower cost, higher yield and shorter reaction time.
