Zinc Cation Supported On Carrageenan Magnetic Nanoparticles: A Novel, Green And Efficient Catalytic System For One-Pot Three-Component Synthesis Of Quinoline Derivatives

This is the first report of supporting zinc cation on lambda-carrageenan/Fe3O4 magnetic nanoparticles. The structural and magnetic properties of this hybrid (Zn2+/lambda-carrageenan/Fe3O4 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.
