Article abstract of DOI:10.1002/ejoc.200300353

N-benzyl- and N-methyl-N-glycosylhydroxylamines 3a-i were conveniently obtained by reaction of sugars with N-substituted hydroxylamines according to a novel procedure. Subsequent oxidation occurred at the alkyl group, selectively affording the correspondi
