Kluge, R.; Schulz, M.; Liebsch, S. published an article on February 19 ,1996. The article was titled 《Diastereoselective Epoxidation of Olefins by Organo Sulfonic Peracids. II》, and you may find the article in Tetrahedron.Name: 3-Nitro-1-tosyl-1H-1,2,4-triazole The information in the text is summarized as follows:
The behavior of sulfonic peracids (generated in situ) toward olefins, allylic alcs., homoallylic alcs., and α,β-unsaturated ketones was studied. For example, 4-methylbenzenesulfonoperoxoic acid was generated in situ from 1-(4-methylphenylsulfonyl)-1H-imidazole and trimethyloxonium tetrafluoroborate. Epoxidation of α-pinene with 4-methylbenzenesulfonoperoxoic acid gave 2α,3α-epoxypinane. Generally, the epoxidation proceeds in a peracid-like manner with greater diastereoselectivity than those by common oxidants. In particular, the epoxidation of Δ4 3-ketosteroids gave 4α,5α-epoxides with good diastereoselectivity. Enhanced α-selectivity was also found in the epoxidation of a cholesterol derivative The results came from multiple reactions, including the reaction of 3-Nitro-1-tosyl-1H-1,2,4-triazole(cas: 77451-51-5Name: 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 Name: 3-Nitro-1-tosyl-1H-1,2,4-triazole
