A series of the hydrazones were prepared by the reaction of 3-hydrazino-5H-1,2,4-triazino[5,6-b]indole (1) with monosaccharides, and their acetylation was studied. Cyclodehydrogenation of the hydrazones gave 3-(substituted)-10H-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indole, whose acetylation and partial acetylation were carried out. The ring-chain tautomerism of the hydrazones promoted their
