Synthesis of isoxazolium salts unsubstituted in the 3-position was written by Wilson, B. D.;Burness, D. M.. And the article was included in Journal of Organic Chemistry in 1966.Recommanded Product: 5765-44-6 This article mentions the following:
A variety of isoxazoles unsubstituted in the 3-position were prepared and alkylated to form highly reactive isoxazolium salts, which are potentially useful as peptide bond-forming reagents. A few are inner salts related to Woodward’s reagent K. The explosive nature of isoxazolium perchlorates is revealed. In the experiment, the researchers used many compounds, for example, 5-Methylisoxazole (cas: 5765-44-6Recommanded Product: 5765-44-6).
5-Methylisoxazole (cas: 5765-44-6) belongs to isoxazole derivatives. Isoxazole are described as inhibitors of acetylcholinesterase (AChE). Isoxazole ligands bind to and inhibit the Sxc- antiporter. The most common methods for N–O bond cleavage in isoxazoles are hydrogenation with palladium or platinum catalysts or with Raney Ni. Recent developments have shown that Mo(CO)6 efficiently cleaves the N–O bond in isoxazoles.Recommanded Product: 5765-44-6
