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

The conversion of enantiomerically enriched (ee >99%) 2α-hydroxypinan-3-one and its oxime (obtained in previously described procedures∗ from α-pinene of 65% ee) into a range of derivatives with potential application in asymmetric synthesis was attempted. C2-Symmetrical compounds, ligands for potential catalysts, were synthesized from 2α-hydroxypinan-3-one and either aliphatic or aromatic diamines.
