A Facile, One-Pot Synthesis of 1,4-Dihydropyridine Derivative by Using Polyaniline Supported Zinc Oxide Nanoparticle via Hantzsch Reaction

Polyaniline-supported zinc oxide nanoparticle is very effective for synthesizing poly-hydro quinoline derivatives in a one-pot multi-component reaction through Hantzsch reaction (4a-l). The green and reusable method is described for a multi-component synthesis of 1, 4-dihydropyridine derivatives via the Hantszch reaction. The heterogeneous nanoparticle was characterized by SEM, XRD, UV, FT-IR, and 1H NMR techniques. The method presented here is developing very simple, environmentally benign, less time and best yield. Also, the catalyst can be recovered as well as reused efficiently.
