(Table). A reaction mechanism for the formation of these scarcely investigated thiazole derivatives is formulated in Scheme 3:1,3-Dipolar azide cycloaddition onto the C=S group of 2 leads to the 1 : 1 adduct C. Successive elimination of N, and S yields 6, probably uiu an intermediate thiaziridine E.
ChemInform Abstract Organic azides (II) react with the thiazolethiones (I) in toluene at 90 rc C to give the thiazolimines (III). A reaction mechanism for the formation of these scarcely investigated thiazole derivatives is discussed in detail.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
