Acetylated and benzoylated dimeric dehydroascorbic acid have the same molecular structure as the crystalline parent compound.X-Ray analysis of the tetraacetate reveals only moderate deviation from tw-fold symmetry, caused, presumably, by the packing requirements of the acetate groups.The central dioxane ring is stabilised by the conversion of OH into OAc or OBz.In methyl sulfoxide or N,N-dimethylformamide solutions, no anomerisation occurs as is found with dehydroascorbic acid.
