| Abstract: | Abstract Deoxy-N-hydroxyaminosugars constitute a novel family of sugars. The interest in them is mainly due to their close structural similarity to natural sugars, coupled, with their easy oxidation to nitroxide free radicals, enabling their study by ESR spectroscopy.1 From the point of view of their chemical reactivity, the hydroxyamino group is an ambident nucleophile possessing complex orbital and topographical factors, which direct its reactivity to either of its heteroatoms. |
