Zinc cation supported on carrageenan magnetic nanoparticles: A novel, green and efficient catalytic system for one‐pot three‐component synthesis of quinoline derivatives

Abstract

This is the first report of supporting zinc cation on ƛ‐carrageenan/Fe 3 O 4 magnetic nanoparticles. The structural and magnetic properties of this hybrid (Zn 2 + /ƛ‐carrageenan/Fe 3 O 4 nanoparticles) were identified using various techniques. This green and efficient catalytic system was applied in the synthesis of biologically important quinolines. The products were obtained in good to high yields (52–95%) from a one‐pot reaction procedure involving aromatic aldehydes, enolizable aldehydes and aniline derivatives. Our method has many advantages such as mild reaction conditions, easy work‐up, use of a reusable magnetic catalyst and high yields of products.
