《High-yield synthesis of oligoribonucleotides using o-nitrobenzyl protection of 2′-hydroxyls》 was written by Hayes, J. A.; Brunden, M. J.; Gilham, P. T.; Gough, G. R.. Application In Synthesis of 3-Nitro-1-tosyl-1H-1,2,4-triazole And the article was included in Tetrahedron Letters in 1985. The article conveys some information:

Use of published procedures for photolytic removal of 2′-O-(o-nitrobenzyl) substituents from model oligoribonucleotides results in low yields of fully-deprotected products accompanied by significant amounts of oligomers carrying altered, UV light-resistant residues derived from the 2′-blocking groups. The efficiency of the deprotection has depends on pH; the side-reactions are avoided when the photolysis is carried out in solution buffered at pH 3.5. In the experiment, the researchers used many compounds, for example, 3-Nitro-1-tosyl-1H-1,2,4-triazole(cas: 77451-51-5Application In Synthesis of 3-Nitro-1-tosyl-1H-1,2,4-triazole)

3-Nitro-1-tosyl-1H-1,2,4-triazole(cas: 77451-51-5) belongs to triazoles. Triazoles are an important group of nitrogen-containing five-membered heterocyclic scaffolds. Triazoles are core structures of several drugs and pharmaceutical agents. Triazole derivatives possess antimicrobial, antiparasitic, antidiabetic, analgesic, and anti-inflammatory properties Application In Synthesis of 3-Nitro-1-tosyl-1H-1,2,4-triazole

Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridineOn May 3, 2019 ,《Preparation of 1,5-Dihydropyrazolo[3′,4′:5,6]pyrano[3,4-b]pyridines via a Microwave-Assisted, Palladium-Catalyzed Regioselective C-H Heteroarylation of Electron-Rich Pyrazoles》 appeared in Journal of Organic Chemistry. The author of the article were Garrison, Aaron T.; Childress, Elizabeth S.; Davis, Dexter C.; Lindsley, Craig W.. The article conveys some information:

In the presence of Pd2(dba)3 and SPhos under microwave irradiation, bromopyridinylmethoypyrazoles such as I underwent regioselective arylation to yield dihydropyrazolopyranopyridines such as II; pyrazolobenzopyrans, pyrazolobenzothiopyrans, and two pyrazolonaphthyridinones were prepared using the same method. The cyclization precursors were prepared in two steps from methylpyridines or pyridinemethanols and pyrazolols. In the experimental materials used by the author, we found 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine(cas: 746668-59-7Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine)

6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine(cas: 746668-59-7) belongs to triazoles. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA.Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine
