Abstract

The study focused on creating a novel and environmentally friendly nanocatalyst using cellulose (Cell), β-Cyclodextrin (BCD), graphene oxide (GO), Cu₂O, and Fe₃O₄.The nanocatalyst was prepared by embedding GO and Cu₂O into Cell-BCD hydrogel, followed by the in-situ preparation of Fe₃O₄ magnetic nanoparticles to magnetize the nanocomposite. The effectiveness of this nanocatalyst was evaluated in the one-pot, three-component symmetric Hantzsch reaction for synthesizing 1,4-dihydropyridine derivatives with high yield under mild conditions. This novel nanocatalyst has the potential for broad application in various organic transformations due to its effective catalytic activity, eco-friendly nature, and ease of recovery.

Keywords: 1,4-dihydropyridine; Catalyst; Cellulose; Graphene oxide; β-Cyclodextrin.
