assembly of diverse 2,8′- and N1,8′-bis(indolyl) methane derivatives from readily-available starting materials by simply changing the FeIII salt and reaction temperature. Besides, the fast reaction rate, mild reaction conditions, low catalyst cost and easy operations make this methodology quite useful. The synthetic utility was further demonstrated in the biomimetic synthesis of 6,6′-bis-(debromo)-gelliusine
在 DDQ 作为助氧化剂存在下,色胺与无毒 Fe III盐催化的发散脱氢偶联反应得到了发展。值得注意的是,这些转化的特点是通过简单地改变 Fe III盐和反应温度,从容易获得的起始材料中快速、区域选择性地组装多种 2,8'- 和 N1,8'-双(吲哚基)甲烷衍生物。此外,该方法具有反应速率快、反应条件温和、催化剂成本低、操作简单等优点。在 6,6'-双-(debromo)-gelliusine F 的仿生合成中进一步证明了合成效用。
