ABSTRACT
Uronic acids are widely present in natural polysaccharides. Synthetic methods to obtain uronic acid-containing oligosaccharides involve either a post-or preglycosylation oxidation step. For a recent review on oxidation strategies towards uronic acids, see Ref. [1]. Since the carboxylic acid/ester moiety can have a profound in—uence on both the reactivity1 and selectivity (see for an example, Ref. [2])

in a glycosylation, the most applicable strategy has to be selected carefully (for an example of post-glycosylation oxidation, see Ref. [3]).
