  • An Improved Palladium-Catalyzed Conversion of Aryl and Vinyl Triflates to Bromides and Chlorides
    作者:Jun Pan、Xinyan Wang、Yong Zhang、Stephen L. Buchwald
    DOI:10.1021/ol202098h
    日期:2011.9.16
    A facile Pd-catalyzed conversion of aryl and vinyl triflates to aryl and vinyl halides (bromides and chlorides) is described. This method allows convenient access to a variety of aryl, heteroaryl, and vinyl halides in good to excellent yields and with greatly simplified conditions relative to our previous report.
    描述了芳基和乙烯基三氟甲磺酸酯在 Pd 催化下轻松转化为芳基和乙烯基卤化物(溴化物和氯化物)。与我们之前的报告相比,该方法可以方便地获得各种芳基、杂芳基和乙烯基卤化物,产率良好至优异,并且条件大大简化。
  • Nickel‐Catalyzed Conversion of Enol Triflates into Alkenyl Halides
    作者:Julie L. Hofstra、Kelsey E. Poremba、Alex M. Shimozono、Sarah E. Reisman
    DOI:10.1002/anie.201906815
    日期:2019.10.14
    A Ni-catalyzed halogenation of enol triflates was developed and it enables the synthesis of a broad range of alkenyl iodides, bromides, and chlorides under mild reaction conditions. The reaction utilizes inexpensive, bench-stable Ni(OAc)2 ⋅4 H2 O as a precatalyst and proceeds at room temperature in the presence of sub-stoichiometric Zn and either 1,5-cyclooctadiene or 4-(N,N-dimethylamino)pyridine
    开发了镍催化的烯醇三氟甲磺酸酯卤化反应,能够在温和的反应条件下合成多种烯基碘化物、溴化物和氯化物。该反应使用廉价、实验室稳定的 Ni(OAc)2·4 H2 O 作为预催化剂,并在亚化学计量的 Zn 和 1,5-环辛二烯或 4-(N,N-二甲基氨基) 存在下在室温下进行吡啶。

    日期:2010.10.13
    The palladium-catalyzed conversion of aryl and vinyl triflates to aryl and vinyl halides (bromides and chlorides) has been developed using dialkylbiaryl phosphine ligands. A variety of aryl, heteroaryl, and vinyl halides can be prepared via this method in good to excellent yields.

  • Total Synthesis of (−)-Nodulisporic Acid D
    作者:Yike Zou、Jason E. Melvin、Stephen S. Gonzales、Matthew J. Spafford、Amos B. Smith
    DOI:10.1021/jacs.5b04728
    日期:2015.6.10
    A convergent total synthesis of the architecturally complex indole diterpenoid (-)-nodulisporic acid D has been achieved. Key synthetic transformations include vicinal difunctionalization of an advanced α,β-unsaturated aldehyde to form the E,F-trans-fused 5,6-ring system of the eastern hemisphere and a cascade cross-coupling/indolization protocol leading to the CDE multisubstituted indole core.
    结构复杂的吲哚二萜 (-)-nodulisporic 酸 D 的收敛全合成已经实现。关键的合成转化包括先进的 α,β-不饱和醛的邻位双官能化以形成东半球的 E,F-反式融合 5,6-环系统和导致 CDE 多取代吲哚的级联交叉偶联/吲哚化方案核。
  • Ruthenium-Catalyzed Transformation of Aryl and Alkenyl Triflates to Halides
    作者:Yusuke Imazaki、Eiji Shirakawa、Ryota Ueno、Tamio Hayashi
    DOI:10.1021/ja307771d
    日期:2012.9.12
    Aryl triflates were transformed to aryl bromides/iodides simply by treating them with LiBr/NaI and [Cp*Ru(MeCN)(3)]OTf. The ruthenium complex also catalyzed the transformation of alkenyl sulfonates and phosphates to alkenyl halides under mild conditions. Aryl and alkenyl triflates undergo oxidative addition to a ruthenium(II) complex to form eta(1)-arylruthenium and 1-ruthenacyclopropene intermediates, respectively, which are transformed to the corresponding halides.
