The synthesis of highly functionalized nitriles by an alkoxylradical fragmentation of cyclic β-hydroxy azides is described. The alkoxylradicals were generated by reaction of the alcohols with (diacetoxyiodo)benzene and iodine under mild conditions compatible with the presence of sensitive substituents and the protective groups most frequently used in carbohydrate chemistry. To explore the scope and
