The first iridium‐catalyzed intermolecular asymmetric allylic amination reaction with 2‐hydroxypyridines has been developed, thus providing a highly efficient synthesis of enantioenriched N‐substituted 2‐pyridone derivatives from readily available starting materials. This protocol features a good tolerance of functional groups in both the allylic carbonates and 2‐hydroxypyridines, thereby delivering
已开发出首个由铱催化的2-羟基吡啶的分子间不对称烯丙基胺化反应,从而可以从容易获得的起始原料中高效合成对映体富集的N-取代的2-吡啶酮衍生物。该方案的特点是对烯丙基碳酸酯和2-羟基吡啶中的官能团具有良好的耐受性,从而以高达98%的收率和99%ee的产率提供多功能的杂环产物 。
