2-Acetamido-2-deoxyhexuronic acids have been found in Nature as constituents of bacterial polysaccharides, and several syntheses have been reported 1-7. The principal step in these syntheses was catalytic oxidation of an amino sugar derivative to its uronic acid. However, in our hands, these reactions gave unsatisfactory yields. We now report on alternative syntheses of the title compounds, using azidonitration 8 of the corresponding glyeal ...
