چکیده مقاله:
A streamlined and efficient method for the synthesis of ۲-amino-۴H-chromenes is achieved by one-pot three-component reaction of aldehydes, ۲-naphthol and malononitrile in the presence of ZnO nanoparticles loaded on zeolite-Y (ZnO@zeolite-Y) as a highly active catalyst under solvent-free conditions. ZnO@zeolite-Y has been successfully prepared via hydrothermal technique and its structure was confirmed using nanoscale-like identification techniques included FT-IR, XRD, FE-SEM, EDX analyses and BET surface area measurements. The higher environmental compatibility and sustainability factors such as reusability of the catalyst as an important principle in green chemistry, use of solvent-less technique as a green synthetic approach and easy isolation of the product along with good yields, make the present protocol a true green process for the synthesis of chromenes compared to conventional methods.
