  • Cu-Catalyzed Synthesis of Benzoxazole with Phenol and Cyclic Oxime
    作者:Zheng-Hai Wang、Dong-Hui Wang
    DOI:10.1021/acs.orglett.1c04322
    日期:2022.1.21
    A Cu-catalyzed straightforward synthesis of benzoxazoles from free phenols and cyclic oxime esters is reported. The mild reaction conditions tolerate various electron-withdrawing and electron-donating functional groups on both substrates, affording benzoxazoles in moderate to good yields. With this protocol, large-scale syntheses of Ezutromid and Flunoxaprofe in one or two steps are demonstrated. A

    observed, which is different than the normal H/D kinetic isotope effects (KIEs) usually observed for polar aromatics. This result indicated that the oxidation started by photo-induced hvb+ can be the rate-determining step.
    在TiO 2溶液中弱极性芳族化合物的光催化羟基化反应中,观察到一系列的反向H / D KIE为0.7-0.8,这与通常在极性芳族化合物中观察到的正常H / D动力学同位素效应(KIEs)不同。该结果表明,由光诱导的h vb +开始的氧化可以是速率确定步骤。
  • Alkynoxy-Directed C–H Functionalizations: Palladium(0)-Catalyzed Annulations of Alkynyl Aryl Ethers with Alkynes
    作者:Yasunori Minami、Yuki Shiraishi、Tatsuro Kodama、Mayuko Kanda、Kotomi Yamada、Tomohiro Anami、Tamejiro Hiyama

    日期:2015.10.15
    Palladium(0)-catalyzed insertion/annulation sequence between aryl silylethynyl ethers and internal alkynes was found to proceed through activation of ortho-C–H bonds assisted by alkynoxy groups and gave stereoselectively (Z)-2-silylmethylenechromenes. These products could be easily converted into 2,2-alkylated 2H-chromene derivatives, an important structural motif in medicinal chemistry and materials science. Various aryl silylethynyl ethers and alkynes can be transformed under the reaction conditions, and a wide range of chromenes is thus accessible. When unsymmetric alkynes are employed, a regioselective annulation takes place, especially those containing aryl and/or bulky substituents. Catalytic systems based on palladium(0), such as Pd(OAc)2/PCy3/Zn, [Pd(dba)2]/PCy3, or Pd(PCy3)2 exhibit excellent catalytic activity, and the best performance is observed for Pd(PCy3)2 in combination with Zn(OAc)2 as an additive. Substituents on the aryl group in the alkynyl aryl ethers rarely affect the reaction rate. Deuterium-labeling experiments suggest that the ortho-hydrogen atom migrates to the 2-methylene position in the chromene products. The cleavage of the C–H bond is considered to be the rate-determining step in these reactions.
    (0)催化的芳基乙炔醚与内烯的插入/环化反应发现,反应是通过烷炔醇基团辅助的邻位C–H键活化进行的,能够立体选择性地生成(Z)-2-基亚甲基色烯。这些产物可方便地转化为2,2-烷基化的2H-色烯生物,这在医药化学和材料科学中是一种重要的结构单元。在反应条件下,各种芳基乙炔醚和炔烃都可以被转化,因此可以获得广泛的色烯。当使用不对称炔烃时,会发生区域选择性的环化,特别是含有芳基和/或大取代基的情况。基于(0)的催化系统,如Pd(OAc)₂/PCy₃/Zn、[Pd(dba)₂]/PCy₃或Pd(PCy₃)₂展现出卓越的催化活性,并且在Pd(PCy₃)₂与Zn(OAc)₂作为添加剂结合时,表现最佳。阿尔基芳醚中芳基的取代基对反应速率几乎没有影响。标记实验表明,邻位氢原子迁移到色烯产物中的2-亚甲基位置。C–H键的断裂被认为是这些反应的速率决定步骤。
  • Ir-Catalyzed Intramolecular Transannulation/C(sp<sup>2</sup>)–H Amination of 1,2,3,4-Tetrazoles by Electrocyclization

    An efficient strategy for the intramolecular denitrogenative transannulation/C(sp2)-H amination of 1,2,3,4-tetrazoles bearing C8-substituted arenes, heteroarenes, and alkenes is described. The process involves the generation of the metal-nitrene intermediate from tetrazole by the combination of [Cp*IrCl2]2 and AgSbF6. It has been shown that the reaction proceeds via an unprecedented electrocyclization
