  The effect of pre-existing stereocenters in the intramolecular asymmetric Stetter reaction

  摘要：

  A series of disubstituted cyclopentanones have been synthesized by the intramolecular Stetter reaction. Racemic substrates containing one chiral center were used, allowing us the opportunity to observe a parallel kinetic resolution in the synthesis of 2,3- and 2,4disubstituted cyclopentanones. The Stetter reaction of 2,5-disubstituted cyclopentanones proved to be substrate controlled, resulting in the selective formation of the cis-diasteroiners with low ee. (c) 2005 Elsevier Ltd.

  radical (TEMPO) catalytic systems enable efficient aerobic oxidations of primary alcohols but they generally show a reduced reactivity in aqueous medium. Herein, we report an oxidative catalytic system composed of Trametes versicolor laccase and TEMPO, which is able to work in buffer solutions at room temperature using ambient air. Although this catalytic system displays great efficiency in aqueous systems

  铜盐/ 2,2,6,6-四甲基哌啶氧基自由基（TEMPO）催化系统可实现伯醇的有效好氧氧化，但它们通常在水性介质中显示出降低的反应性。在本文中，我们报告了一种由云芝Trametes漆酶和TEMPO组成的氧化催化系统，该系统能够在室温下使用环境空气在缓冲溶液中工作。尽管此催化体系在水性体系中显示出很高的效率，但是添加甲基叔丁基醚可以降低TEMPO的负载量，还可以提高疏水性化合物的溶解度。这种实用的方法可以促进羟基或氨基的化学选择性好氧氧化，从而产生令人感兴趣的有机衍生物，例如醛，内酯，半乳糖或内酰胺。

  found to be a versatile biocatalyst for the desymmetrization of prochiral 3‐arylpentane‐1,5‐diols, based on a two‐step one‐pot oxidation. This procedure has allowed the formation of valuable (S)‐lactones in good to excellent conversions and enantiomeric excess. The catalytic performance of HLADH has been studied using several cofactor regeneration systems and cosolvents, finding great improvements in

  A direct intramolecular anti-Markovnikov hydroetherification reaction of alkenols is described. By employing Catalytic quantities of commercially available 9-mesityl-10-methylacridinium perchlorate and 2-phenyl-malononitrile as a redox-cycling source of a H-atom, we report the anti-Markovnikov hydroetherification of alkenes with complete regioselectivity, In addition, we present results demonstrating that this novel catalytic system can be applied to the anti-Markovnikov hydrolactonization of alkenoic acids.
