Synthesis of polycyclic indole derivatives from 2,4,6-trinitrotoluene

Polycyclic indole derivatives of imidazole and pyrazine series with previously unknown combination of substituents, as well as representatives of the new heterocyclic systems of triazole and furoxan series, were synthesized on the basis of 2-aryl-4-isobutylsulfonyl-6-nitroindoles - products of 2,4,6-trinitrotoluene transformations.
