    Electro-organic Synthesis 68. Diastereoselective Cathodic Reduction of Phenylglyoxylic Acid Attached to Chiral Auxiliaries.
    摘要:
    Two chiral auxiliaries were attached to phenylglyoxylic acid as amides in 67-70% yield. Cyclic voltammetry of one amide in acetonitrile-pivalic acid (0.117 mol l(-1)) shows that it is irreversibly reduced at --0.73 to -1.07 V (vs. Ag/AgCl) depending on the cation of the supporting electrolyte. During preparative-scale electrolysis the amides afforded the corresponding mandelic acid derivatives in 64-76% yield and 52-86% de, respectively. The diastereoselectivities depend on solvent, proton donor, supporting electrolyte, temperature and the substituent R in the 2-oxo acid amides. The results are in accordance with an ECE-reduction of the Zero acid amide to an enolate anion, which subsequently undergoes a face-selective protonation to the mandelic acid amide.

    frequently found in pharmaceutical compounds. To date, there is no strategy for synthesizing N-trifluoromethyl amides from abundant organic carboxylic acid derivatives, which are ideal starting materials in amide synthesis. Here, we report the synthesis of N-trifluoromethyl amides from carboxylic acid halides and esters under mild conditions via isothiocyanates in the presence of silver fluoride at room temperature
    在生物分子、药物和农用化学品中发现的含酰胺分子在自然界中无处不在,它们的衍生化代表了氟化学的重要方法学目标。三氟甲基酰胺已成为药物化合物中常见的重要官能团。迄今为止,还没有从丰富的有机羧酸衍生物合成N-三氟甲基酰胺的策略,有机羧酸衍生物是酰胺合成的理想原料。在这里,我们报告了N的合成-三氟甲基酰胺从羧酸卤化物和酯在温和条件下通过异硫氰酸酯在氟化银存在下在室温下。通过这种策略,异硫氰酸酯用 AgF 脱硫,然后将形成的衍生物酰化以提供N-三氟甲基酰胺,包括以前无法获得的结构。该方法适用范围广,凭借两个反应伙伴的多样性和可用性,为快速生成N-三氟甲基酰胺提供了平台,并应在高级中间体的改性中找到应用。

    DOI:10.1039/c4cc00427b
    日期:——
    The first enantio- and chemoselective Bronsted-acid catalysed reduction of alpha-keto esters with catecholborane has been developed. The alpha-hydroxy esters were obtained under mild reaction conditions in virtually quantitative yields and excellent enantioselectivities. With slight modifications both enantiomers can be obtained without any loss of selectivity.
