%X The structure of the condensation products of
2-hydroxybenzohydrazide, 2-aminobenzohydrazide, and N-methyl-N-(2-aminobenzo) hydrazide 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. The condensation
products of aldoses with 2-hydroxybenzohydrazide and 2-aminobenzohydra- zide in
DMSOd6 solutions exist as
equilibrium mixtures of linear acylhydrazone and cyclic pyranose and furanose
forms. The aldoses condensation products with N-methyl-N-(2-aminobenzo)hy- drazide in the crystalline state and in DMSOd6 solutions have cyclic benzo-1,2,4-triazepin
structure.
