  • One-Pot Transformation of Ph<sub>2</sub>P(O)-Protected Ethynes: Deprotection Followed by Transition Metal-Catalyzed Coupling
    作者:Lifen Peng、Feng Xu、Yoshinori Suzuma、Akihiro Orita、Junzo Otera
    DOI:10.1021/jo402176w
    日期:2013.12.20
    Ph2P(O)-protected ethynes were successfully transformed to arylethynes in one-pot manner through t-BuOK-catalyzed deprotection followed by Sonogashira coupling with aryl halide. The arylethynes were obtained similarly by Ph2P(O)-deprotection, stannylation of the resulting terminal ethynes, and Migita-Kosugi-Stille coupling. Deprotection followed by intramolecular Eglinton coupling could be carried out in one-pot to provide cyclic butadiynes.
  • Selective Deprotection of Me<sub>3</sub>Si-/Ph<sub>2</sub>P(O)-protected Arylalkynes: Methyl Grignard Reagent-promoted Dephosphorylation of Ph<sub>2</sub>P(O)-protected Alkynes

    A Ph2P(O)-protected alkyne underwent dephosphorylation by treatment with MeMgBr in THF with Me3Si-protection untouched. The dephosphorylation followed by a transition-metal-catalyzed coupling of the resulting terminal alkyne with aryl halides was carried out in a one-pot manner to afford the desired coupling product. Selective deprotection of Me3Si-/Ph2P(O)-protected alkynes enabled facile syntheses of expanded π-systems such as cyclic phenyleneethynylenes and unsymmetrically substituted ditriazol.
    一种Ph2P(O)保护的炔烃在THF中用MeMgBr处理后发生去磷酸化,Me3Si保护未受到影响。该去磷酸化后紧接着与芳基卤化物进行的过渡金属催化偶联反应以一锅法进行,从而获得所需的偶联产物。选择性去保护Me3Si-/Ph2P(O)保护的炔烃使得扩展π系统的合成变得简便,例如环状苯乙炔和不对称取代的二三唑。
  • Ph2P(O) Group for Protection of Terminal Acetylenes

    A protecting group Ph2P(O) for terminal ethyne was newly developed. This protecting group can be introduced readily to terminal ethyne by CuI-catalyzed phosphination and subsequent oxidation with H2O2. Ph2P(O)-protected ethynes remained intact in Sonogashira coupling, and their high polarity enabled easy separation of the desired coupling product from by-products. By treatment with t-BuOK, Ph2P(O)-protected
    新开发了末端乙炔保护基Ph 2 P(O)。该保护基可以通过CuI催化的磷酸化并随后用H 2 O 2氧化而容易地引入末端乙炔。在Sonogashira偶联中,Ph 2 P(O)保护的乙炔保持完好无损,并且它们的高极性使得可以轻松将所需的偶联产物与副产物分离。通过用t -BuOK处理,Ph 2 P(O)保护的乙炔转化为相应的末端乙炔。 炔烃-磷酸化-保护基-偶联
