In 2016,Aitha, Anjaiah; Yennam, Satyanarayana; Behera, Manoranjan; Anireddy, Jaya Shree published 《Design and synthesis of diaziridinyl quinone thiadiazole hybrids via nitrile sulfide cycloaddition reaction as a key step》.Tetrahedron Letters published the findings.Quality Control of 3-(Trifluoromethyl)-1H-pyrazole The information in the text is summarized as follows:
A series of novel diaziridinyl quinone thiadiazole hybrids (I; R = N-heterocycle) were synthesized starting from 2-hydroxy-5-methoxybenzoic acid in a 7 step synthetic sequence. The key step in the scheme involves the nitrile sulfide cycloaddition reaction of oxathiazolone II with p-tosyl cyanide to obtain 1,2,4-thiadiazole derivative III. We have demonstrated that p-tosyl group of thiadiazole 5 can be displaced with various nitrogen heterocycles to generate unknown 3,5-disubstituted thiadiazole derivatives In the experiment, the researchers used 3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4Quality Control of 3-(Trifluoromethyl)-1H-pyrazole)
3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4) belongs to pyrazoles. The application of pyrazole derivatives in the development of anticancer agents has been thoroughly investigated and verified. Moreover, the medicinal features of a number of natural products incorporating pyrazole moiety such as pyrazofurin, pyrazofurin B, pyrazole-3(5)-carboxylic acid and 4-methylpyrazole-3(5)-carboxylic acid have been reported.Quality Control of 3-(Trifluoromethyl)-1H-pyrazole
