  • Diastereoselective Aldol and Reformatsky Reactions of<b><i>α</i></b>-Halo Carbonyl Compounds and Aldehydes Mediated by Titanium(II) Chloride
    作者:Akifumi Kagayama、Koji Igarashi、Isamu Shiina、Teruaki Mukaiyama
    DOI:10.1246/bcsj.73.2579
    日期:2000.11
    Highly diastereoselective aldol reactions of α-bromo ketones with several aldehydes were successfully carried out by using a combination of titanium(II) chloride and copper or sodium iodide in dichloromethane-pivalonitrile at low temperature. Similarly, Reformatsky reactions of α-bromo thioester with aliphatic aldehydes proceeded to afford β-hydroxy thioesters in good yields under mild conditions.
    通过在低温下在二氯甲烷-新戊腈中使用氯化钛 (II) 和碘化铜或碘化钠的组合,成功地进行了 α-溴酮与几种醛的高度非对映选择性羟醛反应。类似地,α-溴硫酯与脂肪醛的 Reformatsky 反应在温和条件下以良好的产率得到 β-羟基硫酯。
  • Chiral Phosphoramide-Catalyzed Aldol Additions of Ketone Enolates. Preparative Aspects
    作者:Scott E. Denmark、Robert A. Stavenger、Ken-Tsung Wong、Xiping Su
    DOI:10.1021/ja984123j
    日期:1999.6.1
    Trichlorosilyl enolates of ketones (enoxytrichlorosilanes) were demonstrated to be highly reactive aldol addition reagents. Trichlorosilyl enolates of cyclohexanone (E-enolate) and propiophenone (Z-enolate) reacted readily at room temperature with a wide variety of aldehydes to afford aldol addition products in high yield and diastereoselectivity (E → syn, Z → anti). These reactions were shown to be
    酮的三氯甲硅烷基烯醇化物(烯氧基三氯硅烷)被证明是高度反应性的羟醛加成试剂。环己酮(E-烯醇化物)和苯丙酮(Z-烯醇化物)的三氯甲硅烷基烯醇化物在室温下很容易与多种醛反应,以高产率和非对映选择性(E→syn,Z→anti)得到羟醛加成产物。这些反应被证明对催化量的手性磷酰胺的加速非常敏感。特别是,衍生自 (S,S)-芪二胺的磷酰胺不仅在加速反应方面显着有效,而且在调节非对映选择性和提供具有良好至优异对映选择性的羟醛加成产物方面也非常有效。未促进过程的非对映选择性已被解释为通过五配位、三角双锥 (tbp) 硅配合物通过船状过渡结构进行反应的结果。磷酰胺催化的反应更复杂,...
  • Anti-selective and regioselective aldol addition of ketones with aldehydes using MgI2 as promoter
    作者:Han-Xun Wei、Richard L. Jasoni、Huawu Shao、Jiali Hu、Paul W. Paré
    DOI:10.1016/j.tet.2004.09.098
    日期:2004.12
    The first example of a direct aldehyde–ketone coupling using the secondary amine piperidine as base in the presence of MgI2 to generate high selectivity of anti-aldol products from unmodified ethyl ketones in high yield is reported. The coupling reactions were carried out in a one-pot reaction by mixing four reaction components at room temperature. In the case of unsymmetrical ketones, addition was
    报道了在MgI 2存在下使用仲胺哌啶为碱直接醛-酮直接偶联,以高产率从未改性的乙基酮中产生高选择性的抗醛醇缩合产物的第一个例子。通过在室温下混合四种反应组分以一锅法进行偶联反应。在不对称酮的情况下,在受阻较少的α侧添加了酮。
  • Gallium(III) Triflate Catalyzed Diastereoselective Mukaiyama Aldol Reaction by Using Low Catalyst Loadings
    作者:Baptiste Plancq、Lyse Carole Justafort、Mathieu Lafantaisie、Thierry Ollevier
    DOI:10.1002/ejoc.201301100
    日期:2013.10
    A mild method for the diastereoselective Mukaiyama aldol reaction is reported. By using a low loading of the gallium(III) triflate catalyst (down to 0.01 mol-%), the transformation proceeds efficiently to afford the corresponding β-hydroxy ketones in yields up to 92 %. To the best of our knowledge, this is the first report of a metal triflate acting as a safe, bench-stable, and slow-releasing source
    报道了非对映选择性 Mukaiyama 醛醇反应的温和方法。通过使用低负载量的三氟甲磺酸镓 (III) 催化剂(低至 0.01 mol-%),转化有效地进行,以高达 92% 的产率提供相应的 β-羟基酮。据我们所知,这是首次报道金属三氟甲磺酸盐可作为安全、长期稳定且缓慢释放的三氟甲磺酸来源,用于向山羟醛反应。
