In chemistry, a multi-component reaction (MCRs), or multi-component assembly processes (MCAPs), are a chemical reaction that three or more compounds react together to form a single product. Multicomponent reactions have privileged properties such as selectivity, simplicity, high atom economy, synthesis of complex molecules, and efficiency of the protocol. This strategy is robust methods for the synthesis of pharmaceuticals and biological compounds and has a decisive role in polymer synthesis, supramolecular systems and etc. [1-2]. Polymeric systems due to theirs high reactivity, selectivity, recovering and reusability and adjustable shapes, have an excellent catalytic potential in multicomponent reactions. A major method for the synthesis of 2′‑aminobenzothiazolomethylnaphthols is the multicomponent concentration of aromatic aldehydes with 2-aminobenzithiazole and β-naphthol in the presence of a catalyst. The resulting product is a very interesting research field due to its widespread use in the pharmaceutical applications [4-5]. Herein, a new porous polymeric catalyst was synthesized and was used in the synthesis of 2′‑aminobenzothiazolomethylnaphthols.
