  • Synthesis of Benzyl-, Allyl-, and Allenyl-boronates via Copper-Catalyzed Borylation of Alcohols
    作者:Lujia Mao、Kálmán J. Szabó、Todd B. Marder
    DOI:10.1021/acs.orglett.7b00256
    日期:2017.3.3
    Alcohols are among the most abundant and readily available organic feedstocks in industrial processes. The direct catalytic functionalization of sp3 C–O bonds of alcohols remains the main challenge in this field. Here, we report a copper-catalyzed synthesis of benzyl-, allyl-, and allenyl-boronates from benzylic, allylic, and propargylic alcohols, respectively. This protocol exhibits a broad reaction
    酒精是工业过程中最丰富,最容易获得的有机原料之一。醇的sp 3 C–O键的直接催化官能化仍然是该领域的主要挑战。在这里,我们报道了分别由苄基,烯丙基和炔丙基醇的铜催化的苄基,烯丙基和烯丙基硼酸酯的合成。该方案在温和的条件下(包括用于制备仲烯丙基硼酸酯)表现出宽泛的反应范围(40个实例)和高效(高达95%的产率)。初步的机理研究表明,该反应涉及亲核取代。
  • Copper(I)-Catalyzed Substitution of Propargylic Carbonates with Diboron: Selective Synthesis of Multisubstituted Allenylboronates
    作者:Hajime Ito、Yusuke Sasaki、Masaya Sawamura
    DOI:10.1021/ja806602h
    日期:2008.11.26
    A versatile synthetic method for the preparation of the allenylboronates, Cu(I)-catalyzed reaction of propargylic carbonates with a diboron, is described. A Cu(O-t-Bu)-Xantphos catalyst system was effective for the preparation of various allenylboron compounds, allenylboronates with different substitution patterns, those with functional groups, and an axially chiral one. The Lewis acid promoted stereoselective addition to aldehydes leading to homopropargylic alcohols showed the usefulness of the new allenylboronates.
  • Iron‐Catalyzed Borylation of Propargylic Acetates for the Synthesis of Multisubstituted Allenylboronates
    作者:Aitor Bermejo‐López、Wei‐Jun Kong、Pedro J. Tortajada、Daniels Posevins、Belén Martín‐Matute、Jan‐E. Bäckvall

    borylation of propargylic acetates. The reaction is highly efficient, occurs under mild conditions, and is easy to scale up. The reaction is stereospecific and occurs with anti-SN2‘ displacement of the acetate by boron, which allows a transfer of chirality. Several transformations including propargylation and further additions highlight the synthetic utility of this reaction.
    多取代的联烯基硼酸酯很容易通过炔丙基乙酸酯的铁催化硼酸化获得。该反应效率高,条件温和,易于放大。该反应是立体有择的,发生时乙酸盐被硼反-S N 2' 置换,从而允许手性转移。包括炔丙基化和进一步添加在内的几种转化突出了该反应的合成效用。
