  Interfacial supramolecular biomimetic epoxidation catalysed by cyclic dipeptides

  摘要：

  We synthesised a library of cis- and trans-cyclic dipeptides and evaluated their efficacy as catalysts in the asymmetric Weitz-Scheffer epoxidation of trans-chalcone. A thorough investigation relying on structure-activity studies and computational studies provided insights into the mechanism of the process. Our results revealed some structural features required for efficient conversion and for introduction of chirality into the product. The cyclic dipeptide acts as a catalyst by templating a supramolecular arrangement at the aqueous-organic interface required for efficient transformations to occur. Among all cyclic dipeptides investigated, cyclo(Leu-Leu) was the most efficient supramolecular catalyst.[GRAPHICS].

  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。

• Diketopiperazine-derived hydroperoxide for chemoselective oxidations of sulfides and enantioselective Weitz–Scheffer epoxidations

  L-Proline-derived hydroperoxide (-)-2, which was obtained from the corresponding diketopiperazine by irradiation under oxygen atmosphere, was applied to the oxidation of a variety of sulfides and asymmetric Weitz-Scheffer epoxidations of cyclic and acyclic enones. The sulfoxidation, however, gave only racemic products. In contrast, depending on the base catalyst, enantio selectivities up to 37% were achieved in the epoxidation of chalcone with (-)-2.
