  • Cobalt-Catalyzed Hydroboration of Terminal and Internal Alkynes
    作者:María J. González、Felix Bauer、Bernhard Breit
    DOI:10.1021/acs.orglett.1c02854
    日期:2021.11.5
    A novel methodology to access synthetically versatile vinylboronic esters through a ligand-controlled cobalt-catalyzed hydroboration of terminal and internal alkynes is reported. The approach relies on the in situ reduction of Co(II) by H-BPin in the presence of bisphosphine ligands generating catalytically active Co(I) hydride complexes. This procedure avoids the use of stoichiometric amounts of base
    报道了一种通过配体控制的钴催化的末端和内部炔烃的硼氢化反应获得合成通用乙烯基硼酸酯的新方法。该方法依赖于H-BPin 在双膦配体存在下原位还原 Co(II),生成具有催化活性的 Co(I) 氢化物复合物。该程序避免使用化学计量量的碱,并且不会产生含硼副产物,这转化为高官能团耐受性和原子经济性。
  • Hexamethyldisilazane Lithium (LiHMDS)-Promoted Hydroboration of Alkynes and Alkenes with Pinacolborane
    作者:Jichao Liu、Caiyan Wu、Tinghui Hu、Wei Yang、Yaoyao Xie、Yinyin Shi、Qianrui Liu、Yinlin Shao、Fangjun Zhang
    DOI:10.1021/acs.joc.1c03012
    日期:2022.3.4
    Lithium-promoted hydroboration of alkynes and alkenes using commercially available hexamethyldisilazane lithium as a precatalyst and HBpin as a hydride source has been developed. This method will be appealing for organic synthesis because of its remarkable substrate tolerance and good yields. Mechanistic studies revealed that the hydroboration proceeds through the in situ-formed BH3 species, which
    使用市售的六甲基二硅氮烷锂作为预催化剂和 HBpin 作为氢化物源,锂促进了炔烃和烯烃的硼氢化反应。该方法因其出色的底物耐受性和良好的收率而对有机合成具有吸引力。机理研究表明,硼氢化通过原位形成的 BH 3物种进行,其作用是推动炔烃和烯烃硼氢化的周转。
  • Copper(I)‐Catalyzed Regioselective Monoborylation of 1,3‐Enynes with an Internal Triple Bond: Selective Synthesis of 1,3‐Dienylboronates and 3‐Alkynylboronates
    作者:Yusuke Sasaki、Yuko Horita、Chongmin Zhong、Masaya Sawamura、Hajime Ito
    DOI:10.1002/anie.201007182
    日期:2011.3.14
    Hooray for hydroboration! The products afforded by the title reaction depend on the substitution pattern on the double bond moiety of 1,3enyne substrates (see scheme). These types of products, either 1,3‐dienylboronates or 3‐alkynylboronates, are difficult to obtain by other methods. Interestingly, ligand‐controlled borylation was observed with high selectivity in some cases. pin=pinacolato, THF=tetrahydrofuran
    硼氢化硼的万岁!标题反应提供的产物取决于1,3-烯炔底物双键部分的取代方式(参见方案)。这些类型的产品(1,3-二烯基硼酸酯或3-炔基硼酸酯)很难通过其他方法获得。有趣的是,在某些情况下,以高选择性观察到配体控制的硼化作用。pin =频哪醇,THF =四氢呋喃。
  • Copper-Catalyzed Highly Regio- and Stereoselective Directed Hydroboration of Unsymmetrical Internal Alkynes: Controlling Regioselectivity by Choice of Catalytic Species
    作者:Kazuhiko Semba、Tetsuaki Fujihara、Jun Terao、Yasushi Tsuji
    DOI:10.1002/chem.201103612
    日期:2012.4.2
    Taking control of boron: A highly regio‐ and stereoselective copper‐catalyzed hydroboration of unsymmetrical internal alkynes has been developed. The regioselectivity was successfully controlled by the choice of catalytic species (copper hydride or boryl copper; see scheme).
    控制硼:已经开发出高度区域选择性和立体选择性铜催化的不对称内部炔烃的硼氢化反应。通过选择催化物种(氢化铜或硼基铜;参见方案)成功控制了区域选择性。
