Oxidative Cyclization of 4-(2-Mercaptophenyl)-Substituted 4H-1,2,4-Triazolium Species to Tricyclic Benzothiazolium Salts was written by Ardon-Munoz, Luis G.;Bolliger, Jeanne L.. And the article was included in European Journal of Organic Chemistry in 2022.Electric Literature of C19H22F3IO3S The following contents are mentioned in the article:
Herein authors report a generally applicable method for the preparation of N-substituted benzo[4,5]thiazolo[2,3-c][1,2,4]triazol-1-ium salts from air stable precursors. This transformation features selective deprotection of a para-methoxybenzyl protected thiol followed by C-H functionalization of the linked 1,2,4-triazolium salts under oxidative conditions. Using this procedure, authors synthesized a variety of tricyclic thiazolium salts which contain both electron-withdrawing and electron-donating aromatic substituents as well as aliphatic substituents. Authors approach also tolerates many functional groups including alkynes, alcs., diols, amides, and polyethers. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Electric Literature of C19H22F3IO3S).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.Electric Literature of C19H22F3IO3S
