Abstract:
This review is concerned with recently developed synthetic methods for non-annelated polynuclear heterocyclic systems that incorporate, along with a furazan and(or) furoxan ring, polynitrogen and nitrogen–oxygen heterocycles (1,2,4- and 1,3,4-oxadiazole, 1,2,3- and 1,2,4-triazole, tetrazole, pyrazole,
sym-triazine, 1,2,4,5-tetrazine and so on) linked
via $\mathrm{C}$–
$\mathrm{C}$ or
$\mathrm{C}$=
$\mathrm{N}$ bonds or heteroatomic
$[\mathrm{N}$,
$\mathrm{O}$,
$\mathrm{S}$,
$\mathrm{N}$=
$\mathrm{N}$,
$\mathrm{N}(\mathrm{O})$=
$\mathrm{N}]$ bridges. Methods for preparing assemblies in which a furazan ring and(or) a furoxan ring are linked to one another by
$\mathrm{C}$–
$\mathrm{C}$ bonds or heteroatoms
$(\mathrm{N}$,
$\mathrm{O}$,
$\mathrm{S})$ are surveyed. Potential applications of the synthesized structures as pharmacologically active and high-energy compounds are discussed.
