Preparation of 4′-amino hexopyranose nucleosides from keto nucleosides. An approach to amino nucleoside antibiotics

Abstract
Amino hexopyranose nucleosides were prepared by treatment of the keto group with hydroxylamine hydrochloride followed by acetylation of the resulting oxime. Among other reagents, sodium borohydride–nickel chloride or sodium borohydride–molybdenum(VI) oxide were found to be excellent reductive systems for the facile synthesis of amino hexopyranose nucleosides.
