  N-杂环卡宾（NHC）在胺存在下用各种酰化试剂催化醇的化学选择性酰化†

  摘要：

  这篇前沿文章报道了三种不同的酰基唑鎓离子的合成和完整表征，包括X射线分析。讨论了这些酰基la离子作为胺和醇的酰化试剂的反应性。然而苄胺与酰基唑鎓离子缓慢反应，不会发生苯甲醇酰化反应。然而，在用N-杂环卡宾（NHC）作为催化剂活化醇时，实现了有效的酯化。重要的是，苄基酯的形成是在以下条件下获得的：苄胺由NHC选择性酒精激活后。高水平的DFT计算表明，酒精的活化是通过NHC与酒精之间的强H键形成而发生的，从而增加了酒精的亲核性。对于在NHC催化下氧化生成的酰基la离子而言，卡宾具有双重作用（协同催化）：（a）NHC用于生成酰基zo离子，（b）NHC用于在随后的酰化反应中活化醇步。NHC催化的苯甲酰选择性酰化苯甲醇 在......的存在下 苄胺用三氟乙基和六氟异丙基酯作为酰化剂也可以实现。而且，烯醇乙酸酯作为化学选择乙酰化试剂也显示出高的O-选择性。提供了动力学和机理研究，并提供了氨基醇化学选择性酰化的一些实例。
