  Solid Phase Behavior in the Chiral Systems of Various 2-Hydroxy-2-phenylacetic Acid (Mandelic Acid) Derivatives

  摘要：

  The solid phase behavior of a series of monosubstituted F-, Cl-, Br-, I-, and CH3- and two 2,4-halogen-disubstituted 2-hydroxy-2-phenylacetic acid (mandelic acid) derivatives was investigated. The study includes detailed information about melting temperature, melting enthalpy, Xray diffraction data, as well as selected binary phase diagrams of the respective chiral systems. Aside from the known metastable metastable conglomerates was found.

  A ruthenocenyl phosphino‐oxazoline‐ruthenium complex (RuPHOX−Ru) catalyzed asymmetric hydrogenation of α‐aryl keto acids has been successfully developed, affording the corresponding chiral α‐aryl α‐hydroxy carboxylic acids in high yields and with up to 97% ee. The reaction could be performed on a gram scale with a relatively low catalyst loading (up to 5000 S/C) and the resulting products can be transformed

  Oxidase‐catalyzed kinetic resolution is important for the production of enantiopure 2‐hydroxycarboxylic acids (2‐HAs), which are versatile building blocks for the synthesis of many significant compounds. However, in contrast to that of (R)‐2‐HAs, the production of (S)‐2‐HA is challenging because of the lack of related oxidases. Herein, suitable enzymes were screened systematically through the analysis

  氧化酶催化的动力学拆分对于生产对映体纯的2-羟基羧酸（2-HAs）非常重要，这是合成许多重要化合物的通用构建基块。但是，与（R）-2-HAs相比，由于缺乏相关的氧化酶，（S）-2-HA的生产具有挑战性。在这里，通过分析许多推定的d-乳酸氧化酶序列并鉴定一些所需的特性，系统地筛选了合适的酶。最后，选择氧化葡糖杆菌621H中的d-乳酸氧化酶，具有良好的溶解度，底物谱宽，立体选择性高等优点，可将2-HAs分解为（S）-2-HAs。使用该d-乳酸氧化酶成功生产了多种（S）-2-HAs，其对映体过量值极佳（> 99％）。提出的目标生物催化筛选标准和方法为生产旋光活性化学物质（S）-2-HAs提供了指导原则。

  The invention relates to a method for producing optically active cyanohydrins and the corresponding &agr;-hydroxy-carboxylic acids, starting from an aldehyde, hydrogen cyanide and an optically active vanadyl-salen catalyst, whereby the reaction mixture is reacted at a temperature of between 0 and 60° C. Between 0.8 and 10 equivalents of hydrogen cyanide and between 0.0001 and 0.05 equivalents of vanadyl-salen catalyst in relation to the aldehyde, (concentration of between 0.5 and 4 mol/litre solvent), are preferably used. After said reaction the optically active cyanohydrin or after an acid hydrolysis the corresponding optically active &agr;-hydroxycarboxylic acid can be isolated with a surplus of enantiomers. The vanadium catalyst used in the invention contains a salen ligand, whereby the ratio salen ligand: vanadium (IV) in the catalyst ranges between 1.4:1 and 10:1.
