reaction of azoloannulated [1,2,4,5]tetrazines with guanidine was studied. New 3-guanidinoimidazo[1,2-b]- and 6-guanidino[1,2,4]triazolo[4,3-b] [1,2,4,5]tetrazines were synthesized using the nucleophilic substitution methodology. Compounds with high antibacterial and antiglycation activity were revealed.

Expansion of the tetrazinering has first been found to occur when [1,2,4]triazolo[4,3-b][1,2,4,5]tetrazines were allowed to react with CH-active compounds in acetonitrile in the presence of triethylamine to give the unexpected series of 8,9-dihydro-7H-[1,2,4]-triazolo[4,3-b][1,2,4,6]tetrazepine derivatives.
