This work describes the atropisomeric relationships of 3‐methyl‐5‐(3‐methyl‐5‐phenyl‐1H‐pyrazol‐1‐yl)‐1‐phenyl‐1H‐pyrazol‐4‐amine (2d), which belongs to series 4‐aminobipyrazole derivatives designed as anti‐inflammatory agents. The 1H nuclear magnetic resonance spectra obtained in the presence of a chiral lanthanide shift salt associated to chiral high‐performance liquid chromatography analysis, X‐ray
这项工作描述了3-甲基-5-(3-甲基-5-苯基-1 H-吡唑-1-基)-1-苯基-1 H-吡唑-4-胺(2d)的阻转异构关系被设计为抗炎药的4-氨基联吡唑系列衍生物。在与手性高效液相色谱分析,X射线衍射和分子建模工具相关的手性镧系元素转移盐存在下获得的1 H核磁共振谱图证实了邻双功能化联吡唑2d以aR的混合物形式存在,如阻转异构体。这些结果提供了有用的信息,以了解该衍生物和其他4-氨基联吡唑类似物的药理特性。手性24:463–470,2012. ©2012 Wiley Periodicals,Inc.
