  • Single-Isomer Iodochlorination of Alkynes and Chlorination of Alkenes Using Tetrabutylammonium Iodide and Dichloroethane
    作者:Michael L. Ho、Alison B. Flynn、William W. Ogilvie

    日期:2007.2.1
    The efficient formation of single-isomer, differentially halogenated alkenes and alkanes is described. These structures were generated by treatment of the appropriate alkyne or alkene with tetrabutylammonium iodide in refluxing dichloroethane. This process is highly selective as evidenced by control experiments using ICl. Treatment of the same alkenes and alkynes directly with iodine monochloride resulted
    描述了单异构体,差异卤代烯烃和烷烃的有效形成。这些结构是通过在回流的二氯乙烷中用四丁基碘化铵处理适当的炔烃或烯烃而产生的。如使用ICl的对照实验所证明的,该过程是高度选择性的。用一氯化碘直接处理相同的烯烃和炔烃会生成复杂的,不可分离的区域异构体和立体异构体混合物。机理研究表明,Bu 4 NI反应很可能是通过缓慢生成ICl来进行的。ICl与Bu 4 NI的络合也是关键控制因素,可在这些过程中实现完美的区域选择性,化学选择性和立体选择性。
  • Single-Isomer Trisubstituted Olefins from a Novel Reaction of (<i>E</i>)-β-Chloro-α-iodo-α,β-unsaturated Esters and Amides

    converted to single isomer trisubstituted olefins bearing three different carbon substituents by cross-coupling under reflux. Mechanistic investigations suggest that this process transfers a hydrogen from the boronic acid to the α-position of the substrate and then introduces an aryl group to the β-position of the intermediate template while replacing chloride. The reaction is highly stereoselective
    (E)-β-代-α--α,β-不饱和酯通过在回流下交叉偶联而转化为带有三个不同碳取代基的单一异构体三取代的烯烃。机理研究表明,该过程将氢从硼酸转移到底物的α位置,然后在取代化物的同时将芳基引入中间模板的β位置。该反应是高度立体选择性的,显示出对E-异构体的偏好。该过程通过(E)-β-代-α-芳基-α,β-不饱和酯进行,这些酯被有效地转化为相应的E立体选择性的铃木型反应生成单异构体。所观察到的立体化学显然是通过基酸的中间体实现的。该反应涉及催化循环,其中通过形成联芳基偶联的产物将Pd II还原为Pd 0。
  • Single isomer trisubstituted olefins bearing alkyl groups
    作者:Thivisha Rajagopal、Alison B. Flynn、William W. Ogilvie
    DOI:10.1016/j.tet.2010.09.002
    日期:2010.11
    E-beta-Chloro-alpha-iodo-alpha,beta-unsaturated esters were converted to single isomer trisubstituted olefins bearing alkyl substituents by using and alkyl-Suzuki cross coupling. The process was highly selective, and the products in all cases were isolated as single isomers. Mechanistic investigations indicated that this process transfers a hydrogen from water to the alpha-position of the substrate, and then an alkyl group is introduced to the beta-position of the intermediate template while replacing a chloride.

  • A simple method to prepare single isomer tetrasubstituted olefins by successive Suzuki–Miyaura cross-couplings of E-β-chloro-α-iodo-α,β-unsaturated esters
    作者:Julie Simard-Mercier、Alison B. Flynn、William W. Ogilvie
    DOI:10.1016/j.tet.2008.04.004
    日期:2008.6
    A convenient method of synthesizing tetrasubstituted olefins as single isomers is described. E-beta-Chloro-alpha-iodo-alpha,beta-unsaturatecl esters are first converted into the corresponding E-beta-chloro-alpha,beta-unsaturatedesters using Suzuki-Miyaura coupling reactions with arylboronic acids and alkenylboronic acids. These transformations gave complete selectivity, and proceeded with substitution at the more activated alpha-iodide position. These compounds, isolated as single isomers, were then transformed into tetrasubstituted olefins by Suzuki-Miyaura couplings with arylboronic acids, alkenylboronic acids, and alkyl boranes to afford the corresponding tetrasubstituted olefins as single isomers. During this coupling process, it was discovered that the use of small ligands, such as PMe3 or PEt3, was critical for efficient coupling. The stereochemistry and regiochemistry of the products were unequivocally established using NMR methods. (C) 2008 Elsevier Ltd. All rights reserved.
