    by condensation of hydrazines with the corresponding ketones. In the presence of potassium iodide, I2-mediated oxidative cyclization of diaryl and tert-butyl aryl ketone hydrazones produced 1H-indazoles via direct aryl C–H amination. Under similar reaction conditions, primary and secondary alkyl ketone hydrazones were transformed into 1H-pyrazole products in a reaction involving sp3 C–H amination. This

    An efficient [bis‐(trifluoroacetoxy)iodo]benzene (PIFA)‐mediated oxidative C‐N bond formation is developed for the synthesis of 1H‐indazoles from readily available arylhydrazones. The reaction tolerates a wide range of functional groups and has broad scope of substrates. Moreover, this method is a relative green and reliable method for rapid preparation of substituted 1H‐indazoles under mild conditions

    bond-forming reactions to N-heterocyclic frameworks has been a long-standing interest in organic synthesis. In this work, we develop an electrochemical radical Csp2–H/N–H cyclization of arylhydrazones to 1H-indazoles. The electrochemical anodic oxidation approach was adopted to synthesize a variety of 1H-indazole derivatives in moderate to good yields. HFIP was not only employed as a solvent or the proton donor

    An electrochemical dehydrogenative C–N coupling method has been developed for the synthesis of 1H-indazoles from easily available hydrazones. Various functional groups are compatible with this metal- and oxidant-free protocol which can be carried out on a gram-scale under neutral and mild conditions. This method was applied for the efficient synthesis of anti-tumor compounds. Mechanism studies show

    日期:2014.8
    1H-indazole and derivatives was accomplished on the basis of the iodobenzene-catalyzed intramolecular C–H amination of hydrazones under mild conditions. Reactions of hydrazones derived from ketones and hydrazines with a catalytic amount of iodobenzene in the presence of Oxone as an oxidant in trifluoroacetic acid took place to afford 1H-indazoles in moderate to good yields. A plausible reaction mechanism
