Dehydroascorbic acid is shown to be converted to 2-(threo-1,2,3-trihydroxypropylkartronic acid in aqueous alkaline solutions. The structure of the acid was determined by mass spectrometry of its acyclic Me,Si derivative. Mass spectrometric and chromatographic data are compared with those of related
