摘要

Series of 3-tetra-O-acetyl–β-D-glucopyranosylimino, 6 substituted -1,2,4,5-tetrazine (IV) have been synthesized by the reaction of aryl dihydroformazanes (III) and tetra-O-acetyl-β-D-glucosylimino-isocyanodichloride in refluxing chloroform medium. The aryl dihydroformazans (III) were prepared by the interaction of acid hydrazides (I) and hydrazine hydrate (II) in refluxing ethanol medium in 1:1 proportion. The structures of tetrazines (IV) were confirmed on the basis of elemental analysis and IR, PMR, 13C and mass spectral analysis.
