  钌烯基膦-恶唑啉-钌配合物催化α-取代丙烯酸的不对称加氢

  摘要：

  在5 bar H 2下，使用RuPHOX-Ru作为手性催化剂，对各种α-取代的丙烯酸进行不对称氢化，从而以高达99％的收率和99.9％ee的产率提供相应的手性α-取代的丙酸。该反应可以以克级进行，具有相对较低的催化剂负载量（最高5000 S / C），所得产物（97％，99.3％ee）可用作构建生物活性手性分子的关键中间体。该不对称方案已成功应用于二氢青蒿酸的不对称合成，这是抗疟疾药物青蒿素工业合成所需的关键中间体。

  of carboxylic acids. Herein, we reported the development of a palladium-catalyzed highly enantioselective Markovnikov hydroxycarbonylation of vinyl arenes with CO and water. A monodentate phosphoramidite ligand L6 plays vital role in the reaction. The reaction tolerates a range of functional groups, and provides a facile and atom-economical approach to an array of 2-arylpropanoic acids including several

  不对称羟基羰基化是合成羧酸的最基本但最具挑战性的方法之一。在此，我们报道了钯催化的乙烯基芳烃与 CO 和水的高度对映选择性马尔可夫尼科夫羟基羰基化的发展。单齿亚磷酰胺配体L6反应中起重要作用。该反应耐受一系列官能团，并为一系列 2-芳基丙酸（包括几种常用的非甾体抗炎药）提供了一种简便且原子经济的方法。该催化体系还使乙烯基芳烃与醇发生不对称马尔科夫尼科夫氢烷氧基羰基化反应，得到 2-芳基丙酸酯。机理研究表明，氢化钯是不可逆的，是区域和对映体决定步骤，而水解/醇解可能是限速步骤。

  Many kinds of aromatic nitriles have been hydrolyzed to afford the corresponding amides and carboxylic acids, by the aid of enzyme system of Rhodococcus butanica. This enzymatic hydrolysis can be successfully applied to the kinetic resolution of α-arylpropionitriles, resulting in the formation of (R)-amides and (S)-carboxylic acids.

  (catalytic) asymmetric synthetic methodologies occupy an important position in modern organic synthesis, the catalytic cleavage of a chiral auxiliary remains underdeveloped. We report the Ni(cod)2/bipyr.-catalyzed alcoholysis of N-acyloxazolidinones to deliver esters. The reaction is broad in scope for both N-acyloxazolidinone substrates and alcohol nucleophiles, and displays good functional group tolerance

• Rational Design of CH/π Interaction Sites in a Basic Resolving Agent

  A novel synthetic basic resolving agent, cis-1-aminobenz[f]indan-2-ol (ABI), was rationally designed by introducing effective CH/pi interaction sites to cis-1-aminoindan-2-ol (AI), whose chiral recognition ability has been reported from our laboratory. ABI was applicable to a wide variety of racemic arylalkanoic acids and showed moderate to excellent chiral recognition ability, which was obviously higher than that of AI. The fundamental and important role of CH/pi interactions, such as tunable CH(sp(2))/pi and CH(sp(3))/pi interactions, in the chiral recognition by ABI was revealed by X-ray crystallographic study.
• A separation method for DNA computing based on concentration control

  A separation method for DNA computing based on concentration control is presented. The concentration control method was earlier developed and has enabled us to use DNA concentrations as input data and as filters to extract target DNA. We have also applied the method to the shortest path problems, and have shown the potential of concentration control to solve large-scale combinatorial optimization problems. However, it is still quite difficult to separate different DNA with the same length and to quantify individual DNA concentrations. To overcome these difficulties, we use DGGE and CDGE in this paper. We demonstrate that the proposed method enables us to separate different DNA with the same length efficiently, and we actually solve an instance of the shortest path problems.
