Abstract

Heterocyelic compounds such as pyranopyrazoles display significant roles in medicinal and synthetic chemistry [I]. They showed numerous biological activities such as antibacterial, anticancer [2]. On the other hands, zeolites are alurninosilicates materials that have three dimensional network structured of Sins- and AlQ4- tetrahedral. which provide tile cavities [3]. Acidic zeolite such as HY .. zeolite is unique acid that it contains a framework system of supercages and it bas been used in various chemical transformat ions. Modifying and functionalizing the zeolite surface improves its catalytic properties extremely [4]. Therefore, in this research the functionalized and modified HY zeolite by 2,6-diamino-4-p11enyl-1,3 5-triazine bas been synthsised and then characterized by X .. ray powder diffraction, scanning electron microscopy (FE-SEM), nitrogen adsorption isotherms ( BET) and FTIR spectroscopy analysises .. Finally, due to importance of pyrano pyram le derivat ives, the syntbeised modified zeo lte was used as a novel nad reusable acatalyst in facile and efficient synthesis of some pyrano pyrazole derivatives in mild conditions , short reation times and in according to green chemistry ru Jes.
