Paragraph 0095-0097, (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.

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.

The reaction of sodium or caesium dithiocarboxylates with diphenylthiophosphinic and diphenylselenophosphinic chlorides gives purple thioacyl diphenylthiophosphinoyl 5 and dark green thioacyl diphenylselenophosphinoyl sulfides 6, which are useful thioacylating reagents under mild reaction conditions.Thioacyl diphenylphosphino sulfides 22, which can be obtained by the similar method using diphenylphosphinous chlorides, react with methanol to yield the corresponding methyl dithiocarboxylates 15, while the reactions of 22 with N-chlorosuccinimide lead to hitherto unknown N-(thioacetylthio)succinimides 28.

A number of unsymmetrical acyl thioacyl sulfides have been prepared and characterized by the reaction of piperidinium or sodium dithiocarboxylates with acyl chlorides or by desulfurization reaction of acyl thioacyl disulfides with triphenylphosphine.They are deep blue oils or light green crystals and very unstable thermally and for moisture.The n --> ?* transitions of the thiocarbonyl group of 1 appear in higher wave length region than those of the corresponding symmetrical bis(thioacyl) sulfides .Some reactions with nucleophiles are discussed.It was found that the symmetricallization reaction of these unsymmetrical acyl thioacyl sulfides occurs in the presence of base such as lithium ethanethiolate to give the symmetrical bis(thioacyl) disulfides in fair yield.
