Design and application of modified zeolite-Y as efficient nanocatalysts for the synthesis of heterocycles

Recently, zeolites have attracted increasing interest as ideal supports for homogeneous catalysts due to their high surface area, high thermos-stability, nanoporous crystalline structure, persistence in all organic solvents, less or no corrosion, processes, etc. On the other hand, heterocycles are organic compounds that have atoms of at least two different elements as members of their rings. There are many synthetic heterocyclic systems that are indicative of their importance due to their biological activity and pharmaceutical applications. Herein, modified zeolite-NaY nano-porous were synthesized, characterized and applied for the synthesis of heterocycles such as perimidines, tri-substituted imidazoles, tetra-substituted imidazoles, 2-aminothiazoles, 2-arylbenzimidazoles, thiazolidinones, and chromenes,1-4 respectively (Fig. 1).
