  醇和胺的简单 RuCl3 催化酰胺合成

  摘要：

  开发了一种用于从胺和醇直接合成酰胺的催化剂，该催化剂由经济上有吸引力且易于获得的 RuCl 3 、N-杂环卡宾 (NHC) 和吡啶原位生成。在筛选出的 NHC 前体中，体积较小的前体对适度空间位阻的底物具有更好的产率。在寻找真正的催化中间体时，发现 Grubbs 催化剂在碱性条件下对醇的酰胺化具有活性，这表明由 NHC 配体负载的 Ru 配合物可以催化反应。

• 2-Furanylboronic Acid as an Effective Catalyst for the Direct Amidation of Carboxylic Acids at Room Temperature

  2-Furanylboronic acid has been identified as an inexpensive and effective catalyst for the dehydrative amide formation of carboxylic acids and amines. This transformation can be efficiently carried out at room temperature and is applicable to a wide range of carboxylic acids with primary and secondary amines to afford amides in good to excellent yields.

  N-heterocyclic carbene based ruthenium complex was developed as a highly active precatalyst for the direct amide synthesis from alcohols and secondary amines. Notably, reaction of 1-hexanol and dibenzylamine afforded 60% of the corresponding amide using our catalytic system, while no amide formation was observed for this reaction with the previously reported catalytic systems. Unlike the previously reported

  明确定义的基于N-杂环卡宾的钌络合物被开发为一种高活性的预催化剂，用于由醇和仲胺直接合成酰胺。值得注意的是，使用我们的催化系统，1-己醇和二苄基胺的反应提供了60％的相应酰胺，而与先前报道的催化系统的反应没有观察到酰胺的形成。与先前报道的受较少空间受阻的醇和胺进行酰胺化反应不同，观察到酯中间体的参与。
• Penicillin acylase-catalyzed resolution of amines in aqueous organic solvents

  Penicillin acylase from Alcaligenes faecalis catalyzes the enantioselective acylation of amines with phenylacetamide in a kinetically controlled reaction in water at pH II. Addition of cosolvent to the reaction mixture significantly improved the enantioselectivity in most cases. Penicillin acylase from E. coli also catalyzed the phenylacetylation of amines, but an order of magnitude less efficiently than with the enzyme of A. faecalis. Amine resolution via kinetically controlled acylation competes effectively with hydrolysis of N-acylated compounds and constitutes a synthetically useful alternative to existing lipase-based methods.
