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。

A series of TRPA1 antagonists is described which has as its core structure an indazole moiety. The physical properties and in vitro DMPK profiles are discussed. Good in vivo exposure was obtained with several analogs, allowing efficacy to be assessed in rodent models of inflammatory pain. Two compounds showed significant activity in these models when administered either systemically or topically. Protein
