Abstract:
By comparing proton and electron spin resonance spec­tra of twofold and single oxidized ascorbate and acetylated derivatives therefrom it can be concluded that semi dehydroascorbate as well as dehydroascorbate are of bicyclic structure due to the formation of a furanose ring of their side chain.
