Paragraph 0115-0117, (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.

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.

An organocatalytic protocol for the syntheses of 2-substituted benzoxazoles and benzothiazoles is described from alkyl-/arylanilides and alkyl-/arylthioanilides using 1-iodo-4-nitrobenzene as catalyst and oxone as an inexpensive and environmentally safe terminal oxidant at room temperature in air via oxidative C-H functionalization and C-O/S bond formation. The procedure is simple and general and provides an effective route for the construction of functionalized 2-alkyl-/arylbenzoxazoles and 2-alkyl-/arylbenzothiazoles with moderate to high yields. The synthetic and mechanistic aspects have been described.
ANTIMYCOBACTERIAL THIOBENZANILIDES

, p. 307 - 316 (2007/10/02)
A group of 30 thiobenzanilides active against Mycobacterium kansasii have been synthesized and their 1H NMR and UV spectra and RM values (TLC on silica gel impregnated with methylsilicone oil) have been measured.From the correlation between the chemical shifts of the thioamide proton in the 1H NMR spectra and the Hammett constants it can be concluded that the substituents in both aromatic rings uniformly affect the electron density of the thioamide group.The antimycobacterial activity is probably connected with local molecular parameters and can be considered to be approximately additive with respect to both parts of the molecule.
