  通过焓控制的亲核官能化对嘧啶进行 C2 选择性、官能团发散胺化

  摘要：

  杂芳胺的合成因其在小分子发现中的重要性而一直是有机化学中的一个重要课题。特别是，2-氨基嘧啶代表了一种在生物活性分子中普遍存在的高度特权结构基序，但通过直接功能化引入嘧啶 C2-N 键的一般策略是难以捉摸的。在这里，我们描述了一种用于位点选择性 C-H 官能化的合成平台，该平台提供嘧啶基亚胺盐中间体，然后可以原位转化为各种胺产物。基于机制的试剂设计允许嘧啶的 C2 选择性胺化，开辟了位点选择性杂芳基 C-H 官能化的新范围。

Their catalytic efficiency strongly depends on the type of substituent and is remarkable for derivatives with an electron-withdrawing group, showing reactivity comparable to that of flavinium salts which are the prominent organocatalysts for oxygenations. Because of their high stability

  DOI：10.3987/com-05-10342

  日期：——

  Methoxypyrimidines preferentially add to benzonitrile oxide to give cycloadducts to their C=N double bonds. These, however, lose benzonitrile affording the corresponding pyrimidones. Cycloadditions to their C=C double bonds take place to a very low extent, and products generally undergo a ring opening process which affords the corresponding oximes. Pyrimidones preferentially give addition products

  甲氧基嘧啶优先添加到氧化苯甲腈上，从而在其 C=N 双键上形成环加合物。然而，这些失去苄腈，得到相应的嘧啶酮。它们的 C=C 双键的环加成作用非常低，产物通常会经历开环过程，从而提供相应的肟。嘧啶酮优先为其氮原子提供加成产物，并且仅在 4-嘧啶酮的情况下，其 C=C 双键的环加合物才被分离出来。
