A C-2 regioselective debenzylative cycloetherification/reductive elimination sequence applied to perbenzylated C-allyl iminosugars is described. This NIS/TMSOTf-triggered deprotection was successfully applied to five-, six-, and seven-membered C-allyl iminosugars including 1,2 cis and 1,2 trans stereoisomers. It allows rapid introduction of structural diversity at the key C-2 position in a stereoselective manner exploiting the anchimeric assistance of the intracyclic N-benzyl group, giving access to the 2-acetamido and 2-fluoro d-gluco configured C-allyl iminosugars and to the epimeric d-manno derivative.

N-Benzyl-N-glycosylhydroxylamines were prepared in very good yield via condensation of furanoses and pyranoses with N-benzylhydroxylamine at 110°C for 30 min under solvent-free conditions. These anomeric sugar-hydroxylamines exist in equilibrium with the
