Salicylic Acid-Promoted Three-Component Annulation of Benzimidazoles, Aryl Nitroalkenes and Elemental Sulfur

Herein, a three-component cyclization reaction of benzimidazoles, aryl nitroalkenes and elemental sulfur has been developed. Cheap and easily available salicylic acid found to be an efficient mediator for the present transformation. This protocol provides

Polysubstituted benzimidazothiazole, derivative and synthesis method of polysubstituted benzimidazothiazole

The invention relates to polysubstituted benzimidazothiazole, a derivative and a synthesis method of the polysubstituted benzimidazothiazole. According to the method, in the air atmosphere for the first time, a benzimidazole compound, a beta-nitrostyrolene compound and sulfur powder are promoted to be converted into benzo [4, 5] imidazo [2, 1-b] thiazole and a derivative by an acid, and the prepared benzo [4, 5] imidazo [2, 1-b] thiazole is stable in molecular structure and excellent in chemical property. Reaction raw materials of the synthesis method are cheap and easy to obtain, pretreatmentis not needed, and the atom economy of the reaction is high; only cheap aromatic acid needs to be used in the reaction, environmental pollution is reduced, raw materials are saved, and reaction costis reduced; the whole reaction system is simple, reaction conditions are mild, reaction equipment is less, experimental operation is simple and convenient, and material sources are wide.
