A new route for the synthesis of 2-aminopyridines has been developed that merges C–H functionalization with amide alcoholysis. The key component of this method is the ability of a quinazolinone to template the chemo- and regioselective construction of a latent pyridine ring via site-selective olefinic C–H bond functionalization under Ru(II) catalysis. Thus, highly substituted 2-aminopyridines were
已经开发了一种新的合成2-氨基吡啶的方法,该方法将CH官能团与酰胺醇解反应合并在一起。该方法的关键组成部分是喹唑啉酮能够通过Ru(II)催化下的位点选择性烯烃C–H键官能化来模板化潜在吡啶环的化学和区域选择性结构。因此,以高收率制备了高度取代的2-氨基吡啶。机理研究提供了关键的氧化C–H活化/环化过程的机理的见解。
