  • Alkane desaturation by concerted double hydrogen atom transfer to benzyne
    作者:Dawen Niu、Patrick H. Willoughby、Brian P. Woods、Beeraiah Baire、Thomas R. Hoye

    reaction of simple, unactivated alkanes that is mechanistically unique. We show that benzynes are capable of the concerted removal of two vicinal hydrogen atoms from a hydrocarbon. The discovery of this exothermic, net redox process was enabled by the simple thermal generation of reactive benzyne intermediates through the hexadehydro-Diels–Alder cycloisomerization reaction of triyne substrates. We are not
    烷烃中去除两个邻位原子以生产烃对合成化学家来说是一个挑战。在自然界中,去饱和酶和乙炔酶擅长实现这种必要的化功能化反应,例如在不饱和脂肪酸、类二十烷酸赤霉素和类胡萝卜素生物合成过程中。烷烃烃的转化几乎总是涉及多步反应途径中的一种或多种化学中间体;这些可以是可分离的物质(例如醇或烷基卤化物)或反应性中间体(例如阳离子、烷基自由基或σ-烷基-属物质)。在这里,我们报告了机械上独特的简单、未活化的烷烃的去饱和反应。我们表明苄能够从烃中协同去除两个相邻的原子。这种放热的净化还原过程的发现是通过三炔底物的六-狄尔斯-阿尔德环异构化反应,通过简单的热生成反应性中间体实现的。我们不知道任何单步双分子反应,其中两个原子同时从饱和烷烃转移。计算研究表明在烷烃供体中具有重叠的邻位 C-H 键的优选几何结构。
  • The hexadehydro-Diels–Alder reaction

    produce the highly reactive benzyne intermediate. The reaction conditions for this simple, thermal transformation are notable for being free of metals and reagents. The subsequent and highly efficient trapping reactions increase the power of the overall process. Finally, we provide examples of how this de novo benzyne generation approach allows new modes of intrinsic reactivity to be revealed.
    芳炔(形式上包含-三键的芳香系统)是有机化学中所有反应性中间体中用途最广泛的。它们可以被“捕获”以产生用作药物、农用化学品、染料聚合物和其他精细化学品的产品。在这里,我们探索了一种策略,该策略通过六-Diels-Alder 反应将苄的从头生成与它们原位加工成结构复杂的类产物相结合。在六-Diels-Alder 反应中,1,3-二炔与“亲二炔体”发生 [4+2] 环异构化反应,生成高反应性中间体。这种简单的热转化的反应条件以不含属和试剂而著称。随后的高效捕集反应增加了整个过程的能力。
  • Hydroboration of Arynes Formed by Hexadehydro-Diels–Alder Cyclizations with N-Heterocyclic Carbene Boranes
    作者:Takashi Watanabe、Dennis P. Curran、Tsuyoshi Taniguchi
    DOI:10.1021/acs.orglett.5b01480
    日期:2015.7.17
    N-Heterocyclic carbene boranes (NHC-boranes) hydroborate arynes formed in situ by the hexadehydro-Diels–Alder (HDDA) reactions of triyne precursors. The reaction directly provides functionalized arylborane compounds. The unique feature of the NHC-boranes compared to other boranes is that they hydroborate only the aryne product and not the triyne precursor.
    N-杂环卡宾硼烷(NHC-硼烷硼酸芳烃是由三炔前体的六-狄尔斯-阿尔德(HDDA)反应原位形成的。该反应直接提供官能化的芳基硼烷化合物。与其他硼烷相比,NHC-硼烷的独特之处在于它们仅对硼烷产物加硼酸酯化,而对三炔前体则无化作用。
  • Dichlorination of (Hexadehydro-Diels–Alder Generated) Benzynes and a Protocol for Interrogating the Kinetic Order of Bimolecular Aryne Trapping Reactions
    作者:Dawen Niu、Tao Wang、Brian P. Woods、Thomas R. Hoye
    DOI:10.1021/ol403258c
    日期:2014.1.3
    The efficient dichlorination of benzynes prepared by the hexadehydro-Diels-Alder (HDDA) reaction is reported. Cycloisomerization of a triyne substrate in the presence of dilithium tetrachlorocuprate is shown to provide dichlorinated products A by capture of the benzyne intermediate. A general strategy for discerning the kinetic order of an external aryne trapping agent is presented. It merely requires measurement of the competition between bimolecular vs unimolecular trapping events (here, dichlorination vs intramolecular Diels-Alder (IMDA) reaction to give A vs B, respectively) as a function of the concentration of the trapping agent.
