This paper describes the synthesis of unprecedentedfused nitroazaheterocyclic ring systems. Nitro tricycles with a central 1,2,3-triazole ring were obtained via a nitrene-mediated reaction of azidonitrobis(hetaryl) derivatives under thermolysis. The cyclization proceeded with complete chemoselectivity for the desired N-N bond formation. The key azidonitro bicycles were synthesized through an aromatic
本文描述了前所未有的稠合硝基氮杂杂环系统的合成。具有中心 1,2,3-三唑环的硝基三环是通过氮烯介导的叠氮硝基双(杂芳基)衍生物在热解下的反应获得的。环化以完全化学选择性进行,以形成所需的 NN 键。关键的叠氮硝基双环是通过硝基唑和 3-叠氮基-2-氯吡嗪的芳香亲核取代合成的。
