  DOI：10.1021/op300085w

  日期：2012.5.18

  data, temperature effect and free energy relationships, which are expected to follow predictable laws, were investigated. The kinetics vary over 6 orders of magnitude and follows a perfect Arrhenius law, allowing the determination of the energies, enthalpies, and entropies of activation. Finally, we established a Hammett linear relationship for a series of 16 substituted benzoic acids, leading to a

  使用有机超碱，在DMF中的1,8-双（四甲基胍基）萘（TMGN），通过碘甲烷将对位取代的苯甲酸烷基化作为模型反应，以测试连续流微流体反应器中实验参数的控制质量因为期望通过改变取代基来遵循具有大动力学的完美的二阶动力学。这些条件可以直接用于天然产物酯的合成。由于TMGN与碘甲烷反应缓慢，因此比较了底物，碱和烷基化试剂之间的三种不同混合策略。确定与一组烷基化剂和在不同溶剂中反应的速率常数。为了测试所获得数据的质量，温度效应和自由能关系，预期将遵循可预测的法律进行调查。动力学变化超过6个数量级，并遵循完美的阿伦尼乌斯定律，可以确定激活的能量，焓和熵。最后，我们为一系列16个取代的苯甲酸建立了Hammett线性关系，导致该反应的反应常数ρ为-0.65。所获得动力学的质量使我们可以讨论离群值。用少于0.5mmol的底物获得所有动力学。导致该反应的反应常数ρ为-0.65。所获得动力学的质量使我们可以讨论离群值。用少于0
• Free-Radical-Promoted Site-Selective C–H Silylation of Arenes by Using Hydrosilanes
  作者：Zhengbao Xu、Li Chai、Zhong-Quan Liu

  DOI：10.1021/acs.orglett.7b02717

  日期：2017.10.20

  silylation using hydrosilane was developed. This cross-dehydrogenative silylation enables both electron-rich and electron-poor aromatics to afford the desired arylsilanes in unique selectivity. A “para-selectivity” was observed by examination of over 54 examples. This exceptional orientation is quite different from that in Friedel–Crafts C–H silylation or transition-metal-catalyzed dehydrogenative silylation

  开发了使用氢硅烷的自由基促进的芳基/杂芳基CH硅烷化反应。这种交叉脱氢甲硅烷基化可以使富电子和贫电子的芳族化合物以独特的选择性提供所需的芳基硅烷。通过检查超过54个实例，观察到“对位选择性”。这种特殊的取向与Friedel-Crafts的C-H甲硅烷基化或过渡金属催化的脱氢甲硅烷基化完全不同。
• Esters as Acylating Reagent in a Friedel−Crafts Reaction: Indium Tribromide Catalyzed Acylation of Arenes Using Dimethylchlorosilane
  作者：Yoshihiro Nishimoto、Srinivasarao Arulananda Babu、Makoto Yasuda、Akio Baba

  DOI：10.1021/jo801914x

  日期：2008.12.5

  The Friedel-Crafts acylation of arenes with esters by dimethylchlorosilane and 10 mol % of indium tribromide has been achieved. The key intermediate RCOOSi(Cl)Me(2) is generated from alkoxy esters with the evolution of the corresponding alkanes. The scope of the alkoxy ester moiety was wide: tert-butyl, benzyl, allyl, and isopropyl esters were successful. In addition, we demonstrated the direct synthesis

  已经通过二甲基氯硅烷和10mol％的三溴化铟实现了芳烃与酯的弗瑞德-克来福特酰化。关键中间体RCOOSi（Cl）Me（2）由烷氧基酯生成，并伴随有相应的烷烃生成。烷氧基酯部分的范围很广：叔丁基酯，苄基酯，烯丙基酯和异丙酯是成功的。此外，我们证明了由酯10直接合成丹参戊醇的茚满酮中间体11。
• Arene Cyanation via Cation-Radical Accelerated-Nucleophilic Aromatic Substitution
  作者：Natalie Holmberg-Douglas、David A. Nicewicz

  DOI：10.1021/acs.orglett.9b02678

  日期：2019.9.6

  Herein we describe a cation radical-accelerated-nucleophilic aromatic substitution (CRA-SNAr) of alkoxy arenes utilizing a highly oxidizing acridinium photoredox catalyst and acetone cyanohydrin, an inexpensive and commercially available cyanide source. This cyanation is selective for carbon-oxygen (C-O) bond functionalization and is applicable to a range of methoxyarenes and dimethoxyarenes. Furthermore

  本文中，我们描述了利用高度氧化的cri啶氧化还原催化剂和丙酮氰醇（一种便宜的可商购氰化物源）对烷氧基芳烃进行阳离子自由基加速的亲核芳香取代（CRA-SNAr）。该氰化对于碳-氧（CO）键官能化是选择性的，并且适用于一定范围的甲氧基芳烃和二甲氧基芳烃。此外，计算研究为预测​​甲氧基芳烃阳离子自由基的竞争性CH和CO氰化反应中的区域选择性和化学选择性提供了模型。
• Total Synthesis of (±)-Brussonol and (±)-Komaroviquinone via a Regioselective Cross-Electrophile Coupling of Aryl Bromides and Epoxides
  作者：Anees Ahmad、Antonio C. B. Burtoloso

  DOI：10.1021/acs.orglett.9b02221

  日期：2019.8.2

  The short and stereoselective syntheses of diterpenes (±)-brussonol and (±)-komaroviquinone, via a Ni-catalyzed epoxide ring-opening approach in the presence of aryl halides, is described. Key steps involve the effective preparation of a challenging hemiacetal intermediate in a single operation, followed by a highly efficient BF3·OEt2-catalyzed Friedel–Craft alkylation, to construct the tricyclic skeleton

  描述了在芳基卤化物存在下，通过Ni催化的环氧基开环方法，二萜（±）-布鲁索醇和（±）-komroviquinone的短和立体选择性合成。关键步骤包括在一次操作中有效制备具有挑战性的半缩醛中间体，然后进行高效的BF 3 ·OEt 2催化的Friedel-Craft烷基化反应，以构建这些二萜的三环骨架。合成方法可能为合成含有冰松烷图案的几种天然产物提供一条统一的途径。
