Abstract The syntheses of 6-amino-6-deoxyheptopyranurononitriles related to lincosamine by cyano-amination of 1,2:3,4-di-O-isopropylidene-α- d -galacto-hexodialdo-1,5-pyranose (2) is reported. The procedure described allowed direct cyano-amination in good yield under mild conditions. The high diastereofacial selectivity of the reaction is discussed. Indirect cyano-amination by activation of the corresponding
