  三氯甲基苯基酮对醇的有机催化选择性苯甲酰化：含苯酚或芳香胺官能团的醇的苯甲酰化反选择性

  摘要：

  在室温下，当2-10 mol％的PMDETA有机催化剂存在时，三氯甲基苯基酮苯甲酸酯化还含有酚基的化合物中的伯和仲脂肪醇基团，具有很高的收率和优异的选择性。它也显示了在类似条件下在芳基胺存在下选择性地苯甲酰化氨基芳基链烷醇和伯-仲二醇的伯醇基以及烷基胺的伯氨基的潜力。已经提供了反应的选择性和效率的原理。

• Twisted Amides as Selective Acylating Agents for Hydroxyl Groups under Neutral Conditions:  Models for Activated Peptides during Enzymatic Acyl Transfer Reaction

  The highly twisted amide 2 served as a selective acylating agent; for dials under neutral conditions. The reaction of primary-secondary dials with 2 led to the corresponding primary alkyl monopivalates. For dials containing alcoholic and phenolic hydroxyl groups, alcoholic hydroxyl groups were selectively acylated under neutral conditions, whereas, the opposite selectivity was observed under basic conditions, similar to the cases using acyl halides or acid anhydrides. Although 1 and 3 were unreactive to alcohols, 5-10 having substituent groups at C-4 were reactive to alcohols to give the corresponding acetates or benzoates.

  organocatalyst at room temperature in high yields and excellent selectivity. It also shows the potential to selectively benzoylate primary alcoholic groups of aminoarylalkanols and primary-secondary diols as well as primary amino group of alkyl amines in the presence of aryl amines under similar conditions. A rationale for the selectivity and efficiency of the reaction has been provided.
