  • Copper(I)-Catalyzed Regio- and Stereoselective Intramolecular Alkylboration of Propargyl Ethers and Amines
    作者:Hiroaki Iwamoto、Yu Ozawa、Koji Kubota、Hajime Ito
    DOI:10.1021/acs.joc.7b02071
    日期:2017.10.6
    transformed into multisubstituted alkenes through stereospecific transformations. Mechanistic studies showed that the chemo- and stereoselectivity of copper(I)-catalyzed borylation depends on the type of leaving group. Density functional theory calculations suggested that the regioselectivity of the borylcupration of the alkyne is controlled by the electronic effect of the oxygen atom of the propargyl ether
    已经开发了铜(I)催化带有烷基亲电部分的炔丙基醚和胺的区域和立体选择性分子内烷基化。该反应显示出高的官能团耐受性并得到带有杂环的高度官能化的烯基硼酸酯,其在有机化学中是通用的合成中间体。硼酸酯化产物可以通过立体有择的转化而转化为多取代的烯烃。机理研究表明,铜(I)催化的硼酸酯化反应的化学和立体选择性取决于离去基团的类型。
  • The Boron-Wittig Olefination of Aldehydes and Ketones with Bis[(pinacolato)boryl]methane: an Extended Reaction Scope

    日期:2019.9.8
    The boron‐Wittig olefination of aliphatic and aromatic ketones and aldehydes with bis[(pinacolato)boryl]methane is described. The 2,2‐disubstituted and 2‐monosubstituted alkenylboronic acid esters were obtained on a multigram scale with 35–90 % yield.

  • Rhodium catalysed dehydrogenative borylation of vinylarenes and 1,1-disubstituted alkenes without sacrificial hydrogenation—a route to 1,1-disubstituted vinylboronates
    作者:R. Benjamin Coapes、Fabio E. S. Souza、Rhodri Ll. Thomas、Jonathan J. Hall、Todd B. Marder
    DOI:10.1039/b211789d
    日期:2003.2.20
    The complex trans-[Rh(Cl)(CO)(PPh3)2] (1) is an efficient catalyst precursor for the dehydrogenative borylation of alkenes without consumption of half the alkene substrate by hydrogenation, giving useful vinylboronate esters including 1,1-disubstituted derviatives that cannot be made by alkyne hydroboration.

  • Carboboration of Alkynes with Cyclodextrin-Encapsulated <i>N</i> -Heterocyclic Carbene Copper Complexes
    作者:Zhonghang Wen、Yongmin Zhang、Sylvain Roland、Matthieu Sollogoub
    DOI:10.1002/ejoc.201900246
    日期:2019.4.24
    The carboboration of terminal alkynes was studied with a N‐heterocyclic carbene‐capped α‐cyclodextrin copper(I) complex as catalyst. The intermolecular reaction with CH3I gave linear (L) vinyl boron isomers with high selectivity. The intramolecular reaction with terminal alkynes led to exocyclic vinyl boronates and to an unexpected endocyclic (Z)‐isomer, suggesting an unusual mechanism promoted by
    以N-杂环卡宾封端的α-环糊精铜(I)配合物为催化剂,研究了末端炔烃的碳硼化。与CH 3 I的分子间反应产生具有高选择性的线性(L)乙烯基硼异构体。与末端炔烃的分子内反应导致环外硼酸乙烯基酯和意外的环内(Z)异构体,提示配体促进了异常机理。
  • Synthesis of Functionalized Vinyl Boronates via Ruthenium-Catalyzed Olefin Cross-Metathesis and Subsequent Conversion to Vinyl Halides
    作者:Christie Morrill、Robert H. Grubbs
    DOI:10.1021/jo0345345
    日期:2003.7.1
    using ruthenium-catalyzed olefin cross-metathesis of 1-propenyl pinacol boronate and various alkenes, including functionalized and 1,1-disubstituted alkenes. The resultant boronate cross products are stereoselectively transformed into predominantly Z-vinyl bromides and E-vinyl iodides. The vinyl bromides may be synthesized in a two-step, one-pot synthesis from a variety of olefins, resulting in a Z-selective
