    虽然 π 键的自由基添加已经很好地建立,但对 σ 键的添加却很少被探索。我们发现,在可见光照射下,烷基碘衍生的缺电子基团会添加到双环丁基 (BCB)-硼酸酯复合物的中心应变键上,并以高产率生成 1,3-烷基二取代环丁基硼酸酯,具有完全立体定向性和高产率。立体选择性水平。可以访问新的环丁基取代结构,包括肽和类固醇硼酸酯衍生物。此外,虽然发现使用富电子烷基碘作为自由基前体是无效的,但另一种涉及 BCB-硼酸酯的烷基磺酰化和还原脱磺酰化的替代途径提供了获得简单烷基取代的环丁烷产物的途径。

  • Catalytic Transfer Hydrogenation of Arenes and Heteroarenes
    作者:Coralie Gelis、Arne Heusler、Zackaria Nairoukh、Frank Glorius
    DOI:10.1002/chem.202002777
    日期:2020.11.6
    Transfer hydrogenation reactions are of great interest to reduce diverse molecules under mild reaction conditions. To date, this type of reaction has only been successfully applied to alkenes, alkynes and polarized unsaturated compounds such as ketones, imines, pyridines, etc. The reduction of benzene derivatives by transfer hydrogenation has never been described, which is likely due to the high energy
    转移氢化反应对于在温和的反应条件下还原各种分子非常重要。迄今为止,这种类型的反应仅成功地用于烯烃,炔烃和极化的不饱和化合物,例如酮,亚胺,吡啶等。从未描述过通过转移氢化还原苯衍生物的方法,这很可能是由于高使这些化合物脱芳香化所需的能量屏障。在此背景下,我们开发了一种催化转移氢化反应,用于还原苯衍生物和杂芳烃,从而在不需要压缩氢气的情况下,在室温下形成带有各种官能团的复杂三维支架。
  • Metal-free photoinduced C(sp3)–H borylation of alkanes
    作者:Chao Shu、Adam Noble、Varinder K. Aggarwal

    precious-metal catalysts for C-H bond cleavage and, as a result, display high selectivity for borylation of aromatic C(sp2)-H bonds over aliphatic C(sp3)-H bonds4. Here we report a mechanistically distinct, metal-free borylation using hydrogen atom transfer catalysis5, in which homolytic cleavage of C(sp3)-H bonds produces alkyl radicals that are borylated by direct reaction with a diboron reagent. The reaction
    硼酸及其衍生物是化学科学中最有用的试剂之一,其应用范围涵盖药物、农用化学品和功能材料。催化 CH 硼酸化是将这些和其他硼基团引入有机分子的有效方法,因为它可用于直接官能化原料化学品的 CH 键,而无需底物预活化1-3。这些反应传统上依赖贵金属催化剂进行 CH 键断裂,因此,与脂肪族 C(sp3)-H 键相比,芳族 C(sp2)-H 键的硼化显示出高选择性。在这里,我们报告了使用氢原子转移催化的机械上独特的无金属硼化反应 5,其中 C(sp3)-H 键的均裂产生的烷基自由基通过与二硼试剂直接反应而被硼化。该反应通过基于 N-烷氧基邻苯二甲酰亚胺的氧化剂和氯氢原子转移催化剂之间的紫光光诱导电子转移进行。不同寻常的是,更强的甲基 CH 键优先于较弱的二级、三级甚至苄基 CH 键被硼化。机理研究表明,高甲基选择性是形成氯自由基 - 硼酸盐复合物的结果,该复合物选择性地切割空间不受阻碍的 CH 键。通过使用光致氢原子转移策略,

  • Stereocontrolled Synthesis of 1,5-Stereogenic Centers through Three-Carbon Homologation of Boronic Esters
    作者:Phillip J. Unsworth、Daniele Leonori、Varinder K. Aggarwal

    日期:2014.9.8
    Allylic pinacol boronic esters are stable toward 1,3‐borotropic rearrangement. We developed a PdII‐mediated isomerization process that gives di‐ or trisubstituted allylic boronic esters with high E selectivity. The combination of this method with lithiation–borylation enables the synthesis of carbon chains that bear 1,5‐stereogenic centers. The utility of this method has been demonstrated in a formal

    C–B bond of the γ-dimethylamino tertiary boronic esters can be transformed into a variety of functional groups (C–OH, C–vinyl, C–H, C–BF3), thus giving a diverse selection of 3-aryl-1-aminopropanes, which represent a privileged motif among drug molecules. In situ generated 2-phenyl-azetidinium ylides react with boronic esters to form acyclic γ-dimethylamino tertiary boronic esters. The transformation
