Chempluschem 2024; 89:e202300494. [PMID: 37929843 DOI: 10.1002/cplu.202300494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 10/29/2023] [Accepted: 11/06/2023] [Indexed: 11/07/2023]
Abstract
2-Aminobenzothiazoles are widely used in the fields of pharmaceuticals and pesticides. Herein, we report a metal-free protocol for the preparation of 2-aminobenzothiazoles by a covalent organic framework (COF) catalyzed tandem reaction. In the presence of catalytic amount of phenanthroline-decorated COF (Phen-COF), a variety of 2-aminobenzothiazoles are obtained in excellent yields by the cross-coupling of 2-iodoanilines with isothiocyanates at room temperature in water. In addition, the COF-catalyst is very stable and can be reused at least seven times without loss of its catalytic activity.

Abstract
A facile one-pot, metal-free method for the synthesis of 2-aminobenzothiazoles was developed, which includes an initial reaction of electron-deficient 2-haloanilines with aromatic isothiocyanates and the subsequent intramolecular cyclization of the resulting thioureas through the SNAr mechanism. This one-pot, atom-economical, robust, and scalable method avoids the use of reagents such as acid chlorides and Lawesson's reagent that are difficult to handle.

Abstract
Benzothiazoles have played an important role in the field of biochemistry and medicinal chemistry due to their highly pharmaceutical and biological activity. The development of synthetic processes is undoubtedly one of the most significant problems facing researchers. In this review paper, we provided recent advances in the synthesis of benzothiazole compounds related to green chemistry from condensation of 2-aminobenzenethiol with aldehydes/ketones/acids/acyl chlorides and the cyclization of thioamide or carbon dioxide (CO2) as raw materials, and the future development trend and prospect of the synthesis of benzothiazoles were anticipated.
