Structure of Aldoses Condensation Products with SH-Containing Hydrazides

The structure of the condensation products of thiobenzohydrazide, 2-sulfanylacetohydrazide, 3-sulfanylpropiohydrazide, and 2-sulfanylbenzohydrazide with a series of aldoses (L-arabinose, D-ribose, L-rhamnose, D-galactose, D-glucose, and D-mannose) was studied by 1H- and 13C-NMR spectroscopy.
