Chiral Hydroxylamines. IV. 1-(N-Benzyl-N-hydroxyamino)-2:3;4:5-di-O-isopropylidene-α-D-mannofuranose

The title compound, C₁₉H₂₇NO₆, was synthesized from the reaction of the known D-mannose diacetonide with N-benzylhydroxylamine in the presence of zinc dichloride. The absolute configuration at the anomeric center has been deduced from that of the mannose used in the synthesis. In the crystal, molecules are joined by O-H...O intermolecular hydrogen bonds.
