Formation of N-N bonds may offer an original approach to various nitrogen-containing heterocycles with numerous applications. For this purpose, we found that readily available heteroaromatic amines are appropriate substrates for providing an efficient and innovative approach for the formation of N-N bonds in the presence of iodine (III) reagent in very mild conditions. This method makes it possible to
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。
