Three component reactions of olefins, amines, and sulfur were studied. Thioamidation of styrenes is base-controlled, and 2-phenylethanethioamides and benzothioamides were obtained selectively in the presence of two different bases. This protocol offers a simple and efficient procedure for the synthesis of thioamides.

Paragraph 0150-0152, (2018/11/04)
The invention discloses a thioamide derivative. The structural formula of the thioamide derivative is represented by the formula (I) or the formula (II). The invention also provides a preparation method of the thioamide derivative. According to the preparation method, alkali metal salts are taken as the alkalis, amines are directly coupled with alkenes and sulfur, and by selecting the alkali, twodifferent thioamide derivatives represented by the formula (I) and the formula (II) can be prepared from same raw materials. The provided preparation method has the advantages that the raw materials are cheap and easily available, the synthesis method is simple, and the cost is largely reduced. The provided thioamide derivatives can be used in fields such as bioactive molecules, drug synthesis, and the like, and has a wide application range.
