  中性条件下释放H2的酯和胺合成酰胺

  摘要：

  直接由酯和胺有效合成酰胺是在温和的中性条件下实现的，并释放出分子氢。伯胺和仲胺都可以使用。这种前所未有的、普遍的、对环境无害的反应在中性条件下由脱芳构化的钌-钳形 PNN 络合物均匀催化，并在惰性气氛下在甲苯中进行，具有高周转数（高达 1000）。PNP 类似物不催化这种转化，强调了钳形配体的胺臂的重要性。提出了一种机制，涉及通过吡啶部分的芳构化-脱芳构化和胺臂的半可溶性进行金属-配体合作。

  on multigram scales. Amide synthesis under flow was also extended to a total synthesis of local anesthetic lidocaine, with sequential reactions carried out in two serially linked VFD units. The synthesis could also be executed in a single VFD, in which the tandem reactions involve reagent delivery at different positions along the rapidly rotating tube with in situ solvent replacement, as a molecular

  使用涡流装置（VFD）进行的薄膜流动化学可有效地在剪切作用下对胺进行可扩展的酰化反应，相对于传统的批处理技术，酰胺的收率得到了显着提高。优化的单相流动条件在室温下≤80秒内有效，从而能够以克数形式获得结构多样的酰胺，官能化氨基酸和取代脲。在两个连续连接的VFD单元中进行顺序反应的同时，流动条件下的酰胺合成也扩展为局部麻醉利多卡因的总合成。合成也可以在单个VFD中执行，其中串联反应涉及沿分子快速流转管在不同位置进行试剂输送，并进行原位溶剂置换，这是分子组装生产线工艺。对甲氧基苄胺

  A process for preparing amides by reacting a primary amine and a primary alcohol in the presence of a Ruthenium complex to generate the amide and molecular hydrogen. Primary amines are directly acylated by equimolar amounts of alcohols to produce amides and molecular hydrogen (the only byproduct) in high yields and high turnover numbers. Also disclosed are processes for hydrogenation of amides to alcohols and amines; hydrogenation of organic carbonates to alcohols; hydrogenation of carbamates or urea derivatives to alcohols and amines; amidation of esters; acylation of alcohols using esters; coupling of alcohols with water and a base to form carboxylic acids; dehydrogenation of beta-amino alcohols to form pyrazines and cyclic dipeptides; and dehydrogenation of secondary alcohols to ketones. These reactions are catalyzed by a Ruthenium complex which is based on a dearomatized PNN-type ligand of formula A1 or precursors thereof of formulae A2 or A3.

  一种制备酰胺的方法，包括在Ruthenium配合物的存在下，通过反应一种一级胺和一种一级醇生成酰胺和分子氢。直接用等摩尔量的醇对一级胺进行酰化反应，可以高产率、高周转数地生成酰胺和分子氢（唯一的副产物）。此外，还揭示了将酰胺氢化为醇和胺的方法；将有机碳酸酯氢化为醇的方法；将氨基甲酸酯或尿素衍生物氢化为醇和胺的方法；酯的酰胺化反应；使用酯对醇进行酰化反应；将醇与水和碱偶联形成羧酸；将β-氨基醇脱氢生成吡嗪和环肽；以及将二级醇脱氢生成酮的方法。这些反应由基于A1式或A2式或A3式的去芳香的PNN型配体的Ruthenium配合物催化。
