  2-氨基唑合成中的光氧化还原化学与益生元核酸合成有关

  摘要：

  生命前合理的亚铁氰化物-铁氰化物光氧化还原循环将硫脲氧化转化为氰胺，而HCN被还原同系为中间体，这些中间体要么直接与氰胺反应生成2-氨基唑，要么在系统中失去HCN后有可能这样做。硫脲本身是通过加热硫氰酸铵产生的，硫氰酸铵是 HCN 和硫化氢在紫外线照射下反应的产物。

  摘要：

  描述了一种新的酰胺与稳定反应物的三组分还原芳基化反应（iPrOH和芳基硼酸酯），利用2-吡啶基（Py）导向基团。N-Py-酰胺底物可以很容易地由羧酸和PyNH 2制备，所得的N-Py-1-芳基烷胺反应产物很容易通过用HCl取代HN-Py基团而转化为相应的氯化物。1-芳基-1-氯代烷烃产品可进行取代和交叉偶联反应。因此，获得了将羧酸转化成各种官能团的通用方案。Py‐NH 2副产物可以回收利用。
