Аннотация: Expansion of the tetrazine ring 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

S-TETRAZINE -- MALONODINITRILE -- NUCLEOPHILIC SUBSTITUTION
Аннотация: Derivatives of s-tetrazine containing malonodinitrile, ethyl cyanoacetate, and 1,3-indanedione fragments were synthesized by the nucleophilic substitution of heterocyclic groups in 3,6-diazolyl-1,2,4,5-tetrazines. Coordination compounds of the cyanomethyltetrazine anion with Cu+, Mn2+, and the tetrathiafulvalene radical cation were obtained, and their structures were determined. A transformation of cyanomethyltetrazines to pyrrolo[1,2-b][1, 2, 4, 5]tetrazines catalyzed by metal cations was discovered

PYRIDAZINES -- HETEROCYCLIC SUBSTITUENTS -- CARBORANE MOIETY
Аннотация: The structures and characteristic features of the molecular packing patterns of complexes of pyridazines containing heterocyclic substituents and the carborane moiety with 2,3,5,6-tetrachlorohydroquinone (TCHQ) were investigated. It was shown that TCHQ can form supramolecular assemblies with carborane-containing substituted pyridazines. The stoichiometry and three-dimensional structures of these assemblies depend on the substituents in the pyridazine ring and are formed via O-H⋯N hydrogen bonding between TCHQ and heterocyclic molecules

    Synthesis of novel [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines and investigation of their fungistatic activity / A. V. Korotina, S. G. Tolshchina, R. I. Ishmetova [et al.] // Beilstein Journal of Organic Chemistry. - 2022. - Vol. 18. - P243-250
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A series of novel [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines has been synthesized through oxidation reaction of the corresponding 3,6-disubstituted 1,2,4,5-tetrazines bearing amidine fragments. It is shown that the heterocyclic systems obtained can be modified easily at C(3) position in the reactions with aliphatic alcohols and amines. Also, the reactivity of [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines towards CH-active compounds has been studied. The obtained triazolo[1,5-b]annulated 1,2,4,5-tetrazines proved to be active in micromolar concentrations in vitro against filamentous anthropophilic and zooanthropophilic dermatophyte fungi (Trichophyton, Microsporum and Epidermofiton), which cause skin and its appendages (hair, nails) diseases.
