Herein, we report a chemoselective 1,3‐dipolar cycloaddition reaction between 5‐alkylidene‐ or 5‐arylidene rhodanine derivatives and nitrile oxide generated in situ from dibromoformaldoxime to construct 1,3‐thiazolidine‐2,4‐dione scaffold under mild conditions. This strategy exhibits a distinguished manner to afford thiazolidine derivatives in a simple, rapid and practical route. The results proved that the reaction proceeds through an unpredictable rearrangement and no spirocyclic product is generated. The structures of the target molecules were confirmed by IR, 1H NMR, 13C NMR, mass spectra and unambiguously X‐ray crystal structure analysis.
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.
