General description

2-Aminothiophenol is an organosulfur compound used in the synthesis of urea derivatives.[1]

Application

2-Aminothiophenol was used in the synthesis of 1,5-benzothiazepines derivatives by reacting with 1,3-diphenylpropenone derivatives and using aluminosilicate solid catalysts[2]. It was also used in the synthesis of benzothiazole[3] and 3-(benzothiazol-2-yl)coumarin derivatives[4].

    1,5-Benzothiazepines derivatives were obtained first by starting from 1,3-diphenylpropenone derivatives (chalcones) and 2-aminothiophenol by using aluminosilicate solid catalysts. However, diffusional limitations and the strong adsorption of products on the catalyst are deleterious for catalyst activity and life. Then a structured
