  • Anhydrides as α,β-unsaturated acyl ammonium precursors: isothiourea-promoted catalytic asymmetric annulation processes
    作者:Emily R. T. Robinson、Charlene Fallan、Carmen Simal、Alexandra M. Z. Slawin、Andrew D. Smith
    DOI:10.1039/c3sc50199j
    日期:——
    The asymmetric annulation of a range of α,β-unsaturated acyl ammonium intermediates, formed from isothiourea HBTM 2.1 and anhydrides with either 1,3-dicarbonyls, β-ketoesters or azaaryl ketones gives either functionalised esters (upon ring opening), dihydropyranones or dihydropyridones in good yields (up to 93%) and high enantioselectivity (up to 97% ee).
    一系列α,β-不饱和酰胺铵中间体的不对称环化反应,这些中间体由异硫脲HBTM 2.1与酸酐(带有1,3-二羰基、β-酮酯或氮杂芳基酮)反应形成,可以高产率(高达93%)和高对映选择性(高达97% ee)得到功能化的酯(环打开后)、二氢吡喃酮或二氢吡啶酮。
  • Chiral N-heterocyclic carbene catalyzed annulation of α,β-unsaturated aldehydes with 1,3-dicarbonyls

    Chiral N-heterocyclic carbene catalyzed annulations of ynals and enals with 1,3-dicarbonyls have been described. The two reactions provided direct and efficient methods for enantioselective synthesis of functionalized dihydropyranones. Comparatively, the reactions starting from ynals were atom-economical; furthermore the reactions of enals demonstrated broader substrate compatibility.
    已经描述了手性N-杂环卡宾催化的具有1,3-二羰基的烯醛和烯醛的环。这两个反应为功能化二氢吡喃酮的对映选择性合成提供了直接和有效的方法。相比之下,从自醛开始的反应是原子经济的。此外,烯醛的反应证明了更广泛的底物相容性。
  • Polyhalides as Efficient and Mild Oxidants for Oxidative Carbene Organocatalysis by Radical Processes
    作者:Xingxing Wu、Yuexia Zhang、Yuhuang Wang、Jie Ke、Martin Jeret、Rambabu N. Reddi、Song Yang、Bao-An Song、Yonggui Robin Chi

    Simple and inexpensive polyhalides (CCl4 and C2Cl6) have been found to be effective and versatile oxidants in removing electrons from Breslow intermediates under N‐heterocyclic carbene (NHC) catalysis. This oxidative reaction involves multiple single‐electron‐transfer (SET) processes and several radical intermediates. The α, β, and γ‐carbon atoms of aldehydes and enals could be readily functionalized
    在N-杂环卡宾(NHC)催化下,简单廉价的多卤化物(CCl 4和C 2 Cl 6)是从布雷斯洛中间体去除电子的有效和通用氧化剂。该氧化反应涉及多个单电子转移(SET)过程和多个自由基中间体。醛和烯醛的α,β和γ-碳原子很容易被官能化。考虑到氧化剂的低成本和反应的广泛适用性,这项研究有望大大提高氧化型NHC催化在大规模应用中的可行性。此外,这种以多卤化物为单电子氧化剂的SET自由基新方法将为NHC催化的自由基反应的发展开辟新的途径。
  • Direct β-Activation of Saturated Aldehydes to Formal Michael Acceptors through Oxidative NHC Catalysis
    作者:Junming Mo、Liang Shen、Yonggui Robin Chi
    DOI:10.1002/anie.201302152
    日期:2013.8.12
    mediated by N‐heterocyclic carbenes (NHCs) enables the direct β‐carbon functionalization of saturated aldehydes (see scheme). The reaction proceeds through two sequential oxidative steps to generate α,β‐unsaturated triazolium ester equivalents as formal Michael acceptors, which react with 1,3‐diketones and β‐ketone esters in an enantioselective manner.
    不走弯路:由N-杂环卡宾(NHC)介导的氧化催化作用可实现饱和醛的直接β-碳官能化(请参阅方案)。该反应通过两个连续的氧化步骤进行,以生成α,β-不饱和三唑鎓酯当量形式的Michael受体,它们与1,3-二酮和β-酮​​酯以对映选择性的方式反应。
  • Direct Activation of β-sp<sup>3</sup>-Carbons of Saturated Carboxylic Esters as Electrophilic Carbons via Oxidative Carbene Catalysis
    作者:Bin Liu、Weihong Wang、Ruoyan Huang、Jiekuan Yan、Jichang Wu、Wei Xue、Song Yang、Zhichao Jin、Yonggui Robin Chi
    DOI:10.1021/acs.orglett.7b03650
    日期:2018.1.5
    An N-heterocyclic carbene-catalyzed oxidative LUMO activation of the β-cabons of saturated carboxylic esters is disclosed. This approach allows for efficient asymmetric access to lactams and lactones by directly installing functional groups to the typically inert β-sp3 carbons of saturated esters. The use of HOBt as an additive was found to significantly improve both yields and enantioselectivities
    公开了一种N-杂环卡宾催化的饱和羧酸酯的β-碳的氧化LUMO活化。该方法允许通过直接安装的官能团的典型惰性β-SP高效不对称获得内酰胺和内酯3个饱和酯的碳。发现使用HOBt作为添加剂可显着提高反应的产率和对映选择性。
