  使用过硼酸钠对β-芳基丙酮酸进行氧化脱羰

  摘要：

  在环境温度下，使用过硼酸钠四水合物（SPB）在水溶液中氧化β-芳基-和β-杂芳基丙酮酸，可以得到相应的芳酸，收率很好（68–86％）。温和的条件便于制备热不稳定的酸。特别地，该方法已经用于制备不稳定的5-硝基咪唑-2-基乙酸，由于丙酮酸前体的烯醇化，显然不能使用其他试剂获得该不稳定的5-硝基咪唑-2-基乙酸。尝试在酸性溶液中使用次氯酸钙或SPB进行脱羰反应会生成2-氯甲基衍生物。作为具有生物学意义的分子的前体所需要的新型5-硝基咪唑-2-基乙酸已经被充分表征并转化为已知的酰胺。该酸与Vilsmeier'的反应 试剂产生了烯胺衍生物，而不是预期的vinamidinium盐。这种新颖的反应方式可归因于分子内氢键和良好的共轭作用。

  Mechanism and Mechanism-Based Inactivation of 4-Hydroxyphenylpyruvate Dioxygenase

  摘要：

  Six substrate analogs of 4-hydroxyphenylpyruvate, specifically pentafluorophenylpyruvate, 4-hydroxytetrafluorophenylpyruvate,2-thienylpyruvate, 3-thienylpyruvate, thiophenol oxalate, and p-thiocresoloxalate were synthesized and their interactions with porcine liver 4-hydroxyphenylpyruvate dioxygenase investigated. Both pentafluorophenylpyruvate and thiophenol oxalate are competitive inhibitors of the enzyme with Ki values of 14 and 150 mu M, respectively, but p-thiocresol oxalate has no effect on the enzymic activity. The other three substrate analogs are both substrates and mechanism-based inactivators of the enzyme with the following kinetic characteristics (compound, K-m, V-max, k(mact), K', partition ratio) at pH 6.0, 37 degrees C, and an air atmosphere: 4-hydroxytetrafluorophenylpyruvate, 50 mu M, 1.9 mkat/ kg, 1.5/min, 70 mu M 4.2; 2-thienylpyruvate, 500 mu M, 7.8 mkat/kg, 0.6/min, 400 CLM, 41; 3thienylpymvate, 250 mu M, 2 9 mkatikg, 0.6/min, 300 CLM, 22. When inactivated, the dioxygenase was found to contain per mole of active enzyme, 0.78 mol of label from 3-thienyt3 [3H]pyruvate and 0.85 mol of label from 4-hydroxytetrafluorophenyl-3 [3H]pyruvate. The product formed from the enzyme-catalyzed oxidation of 3-thienylpyruvate was determined to be 3-carboxymethyl-3-thiolene-2-one. The implication of these results to the mechanism of the dioxygenase is considered, (C) 1994 Academic Press, Inc.

• A copper-catalyzed coupling reaction of vinyl halides and carbazates: application in the assembly of polysubstituted pyrroles
  作者：Chengang Zhou、Dawei Ma

  DOI：10.1039/c3cc49724k

  日期：——

  CuI-catalyzed coupling of vinyl halides with carbazates gives N-protected N-alkenylhydrazines, which are condensed with ketones under acidic conditions to give polysubstituted pyrroles. The pyrrole synthesis may go through a similar mechanism with Fischer indole synthesis, which involves a [3,3]-sigmatropic rearrangement and other reactions.

  An artificial biocatalytic cascade for asymmetric synthesis of optically pure unnatural amino acids was developed. This method employed three kinds of enzyme in one‐pot reaction, with great flexibility of the enzyme combination, exhibited a broad substrate spectrum. Using only a catalytic amount of amino donor, the reaction can reach complete conversion with high enan‐tiopurity of both d‐ and l‐ products
