convenient method for synthesis of N-aryl-1H-indazol-3-amine and N-aryl-3H-indazol-3-imine compounds has been described via intramolecular oxidative cyclization of the 2-amino-Nˊ-arylbenzimidamide intermediates by Na2WO4/H2O2 in excellent yields. This procedure has several advantages such as mild reaction conditions, shortreaction time, and excellent yields, making this methodology practical.
已经描述了一种通过N-芳基-1H-吲唑-3-胺和N-芳基-3H-吲唑-3-亚胺化合物的快速方便的合成方法,该方法是通过分子内2-氨基-Naryl-芳基苯甲酰胺酰胺中间体的氧化环化反应。 Na 2 WO 4 / H 2 O 2的产率很高。该方法具有许多优点,例如温和的反应条件,短的反应时间和优异的收率,使得该方法实用。
