Arylazo-glycenosides. Part 7. Syntheses of Amino-sugars from Methyl Arylazo-hexenopyranosides

Reaction of the anhydro-glycopyranosiduloses (1) and (2) with o-nitro- and o,p-dinitro-phenylhydrazine yielded the hydrazones (3)-(6), whereas phenyl- or p-nitrophenyl-hydrazine yielded the phenylazoalkenes (7)-(10), formed by rearrangement of intermediat
