    1,1-二氯-2,2,2-三氟乙烷的三氟乙基化不对称1,3-二炔的合成
    摘要:
    使用乙醇胺作为配体的末端1,3-二炔与1,1-二氯-2,2,2-三氟乙烷(CF 3 CHCl 2)的铜介导反应以中等至良好的产率得到三氟乙基化的不对称1,3-二炔。该反应在温和的条件下进行,并且易于操作。具有较弱的吸电子基团或供电子基团的芳基,以及在1,3-二炔末端的烷基取代基是可容忍的。用该方法合成了三氟乙基化的共轭三炔。成功地实现了三氟乙基化的不对称1,3-二炔的进一步转化以提供三氟乙基取代的1,2,3-三唑和异恶唑作为应用实例。

    通过亚烷基类胡萝卜素重排合成不对称取代的1,3-丁二炔和1,3,5-己三炔。
    摘要:
    不对称取代的1,3-丁二炔和1,3,5-己三炔由市售的醛或羧酸分四个步骤合成。该过程中的关键步骤涉及Fritsch-Buttenberg-Wiechell重排,其中亚烷基类胡萝卜素中间体随后重排为所需的多炔。这种重排在温和的条件下进行,并且可以耐受一系列功能。通常,在程序上容易形成二溴代烯烃前体,再加上重排步骤的有效性,使得该方法成为利用钯或铜催化的传统的二炔和三炔合成方法的有吸引力的替代方法。

  • Modification of the Fritsch–Buttenberg–Wiechell rearrangement: a facile route to unsymmetrical butadiynes
    作者:Erin T Chernick、Sara Eisler、Rik R Tykwinski
    DOI:10.1016/s0040-4039(01)01901-3
    日期:2001.12
    echell rearrangement has been used to form unsymmetrically substituted 1,3-butadiynes from 1,1-dibromo-olefin precursors. The reaction proceeds via lithium–halogen exchange, followed by migration of the aryl or alkynyl moiety to provide the butadiyne framework. The facile formation of the dibromo-olefins in three steps from commercially available aryl aldehydes or carboxylic acid chlorides makes this
    Fritsch–Buttenberg–Wiechell重排的一种修饰已用于从1,1-二溴烯烃前体形成不对称取代的1,3-丁二炔。反应通过锂-卤素交换进行,然后芳基或炔基部分迁移以提供丁二炔骨架。由市售的芳基醛或羧酸氯化物分三步轻松形成二溴代烯烃,使该方法成为传统丁二炔合成方法的有吸引力的替代方法。
  • Chemoselective Cobalt(I)-Catalyzed Cyclotrimerization of (Un)Symmetrical 1,3-Butadiynes for the Synthesis of 1,2,4-Regioisomers

    日期:2019.6.7
    The cobalt(I)-catalyzed cyclotrimerization of (un)symmetrical 1,4-disubstituted 1,3-butadiynes is presented. In the case of unsymmetrical 1,3-butadiynes, this reaction can generate eight 1,2,4-substituted and four 1,3,5-substituted isomers. A single 1,2,4-substituted isomer was formed in excellent yields (up to 99%) and exclusive regioselectivities (>99:1) when symmetrical or a 1,3-butadiyne with an

    The Alder-ene reaction of trialkylsilyl-substituted 1,3-butadiynes with terminal alkenes was investigated utilizing a cobalt-based catalyst, and the results were compared with Alder-ene rections catalyzed by the [CpRu(H3CCN)3]PF6 catalyst. Obviously, the two catalysts gave complementary results of yn-dienes differing in the site where the new carbon–carbon bond was formed. Of particular interest are

  • Cobalt-Catalyzed Regio- and Stereoselective Hydrosilylation of 1,3-Diynes To Access Silyl-Functionalized 1,3-Enynes

    日期:2019.7.5
    A regio- and stereoselective hydrosilylation of 1,3-diynes has been developed relying on catalysts generated from bench-stable Co(acac)2 and dppp ligand. A variety of symmetrical and unsymmetrical 1,3-diynes undergo this transformation, yielding the corresponding silyl-functionalized 1,3-enynes in high yields with excellent regioselectivity. Gram-scale reactions and further transformations of the silyl-containing

  • Cobalt-Catalyzed Regiodivergent Stereoselective Hydroboration of 1,3-Diynes To Access Boryl-Functionalized Enynes
    作者:Hui Leng Sang、Caizhi Wu、Guan Ge Darren Phua、Shaozhong Ge
    DOI:10.1021/acscatal.9b03139
    日期:2019.11.1
    We report a regiodivergent and stereoselective hydroboration of 1,3-diynes with pinacolborane (HBpin) in the presence of cobalt catalysts generated in situ from bench-stable Co(acac)(2) and bisphosphine ligands. These cobalt catalysts were activated by the reactions with HBpin. A range of unsymmetrical and symmetrical 1,3-diynes reacted smoothly with HBpin in the presence of Co(acac)(2)/xantphos to selectively afford enynylboronate products with boron addition to the internal carbon of the 1,3-diyne unit. However, these 1,3-diynes reacted in the presence of Co(acac)(2)/dppf to form enynylboronate products with boron addition to the external carbon of the 1,3-diyne unit. These hydroboration reactions show good functional group compatibility and can be readily scaled up to gram-scales without using a drybox. Deuterium-labeling experiments suggest a cis-addition of HBpin to the less-hindered triple bond of 1,3-diynes. Furthermore, the comparison of the regioselectivity between cobalt-catalyzed hydrosilylation and hydroboration reactions of the same 1,3-diyne substrate suggests that Co(acac)(2)/xantphos-catalyzed regioselective 1,3-diyne hydroboration proceeds through a cobalt-hydride intermediate while Co(acac)(2)/dppf-catalyzed 1,3-diyne hydroboration proceed through a cobalt boryl intermediate.
