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. %K Aldoses 2-Hydroxy- and 2-Aminobenzohydrazides %K Benzo-1 %K 2 %K 4-Triazepines %K Ring-Chain-Ring Tautomerism %U http://www.oalib.com/paper/5266295
