Heterocycles, compounds featuring heteroatoms like nitrogen, sulfur, and oxygen, are integral in fields such as synthesis, pharmacology, and medicine. Among these, benzothiazoles, formed by fusing thiazole with benzene, hold significant prominence. Their unique reactivity, especially at the carbon position between nitrogen and sulfur, has sparked wide interest. Notably, 2-substituted benzothiazoles exhibit diverse biological activities, including anticonvulsant, antimicrobial, and antioxidant properties, making them valuable in drug discovery. This review unveils an array of mesmerizing methods employed by chemists to prepare these compounds using 2-aminothiophenol as one of the precursors with other varied reactants. From novel strategies to sophisticated methodologies, each section of this review provides a glimpse into the fascinating world of synthetic chemistry of 2-substituted benzothiazoles. Delving into the diverse synthetic applications of 2-substituted benzothiazoles, this paper not only enriches our understanding of their synthesis but also sparks the imagination with the possibilities for future advancements.

A novel porous and magnetic nanoparticle, composed of Fe3O4/MCM‐41 functionalized with a kryptofix‐21 crown ether, has been successfully synthesized. This was achieved through the treatment of 3‐chloropropyl functionalized Fe3O4/MCM‐41 with the crown ether, followed by the grafting of Cu (II) onto the material, resulting in the formation of Fe3O4/MCM‐41/kryptofix‐21/Cu. The material's 2D‐hexagonally ordered mesophases were analyzed using small‐angle‐PXRD and TEM‐imaging. The Cu (II)‐anchored porous material, Fe3O4/MCM‐41/kryptofix‐21/Cu, exhibited remarkable catalytic activity in the Click reaction between azides and phenylacetylene, conducted in ethylene glycol/water at a temperature of 70 °C. This reaction led to the synthesis of a diverse range of 1,4‐disubstituted 1,2,3‐triazoles. The catalyst demonstrated excellent recyclability, maintaining its catalytic activity for up to eight cycles without any significant loss. Furthermore, no significant leaching of Cu was observed, highlighting the potential of this magnetically innovative nanoporous catalyst in the regioselective formation of 1,4‐disubstituted 1,2,3‐triazolic compounds.
