  • 4-Stannylcoumarins as Useful Reagents in a New Approach to Neoflavonoids
    作者:Pier Giuseppe Ciattini、Enrico Morera、Giorgio Ortar
    DOI:10.1080/00397919508011837
    日期:1995.9
    Abstract 4-Trimethylstannylcoumarins 2, conveniently obtained from the corresponding 4-triflyloxycoumarins 1, undergo Pd(0)/CuI-cocatalyzed cross-coupling reactions with a variety of aryl iodides to afford 4-arylcoumarins 4 in moderate to good yields. Aryl triflates are less effective as coupling partners.
    摘要 4-三甲基甲锡基香豆素 2 可方便地从相应的 4-三氟甲氧基香豆素 1 中获得,与各种芳基碘化物进行 Pd(0)/CuI 共催化的交叉偶联反应,以中等至良好的产率得到 4-芳基香豆素 4。芳基三氟甲磺酸酯作为偶联伙伴的效果较差。
  • Palladium-Catalyzed Oxidative Heck Coupling Reaction for Direct Synthesis of 4-Arylcoumarins Using Coumarins and Arylboronic Acids

    An efficient protocol for the direct synthesis of 4-arylcoumarins via palladium-catalyzed oxidative Heck coupling reaction of coumarins and arylboronic acids was developed. 4-Arylcoumarins were obtained in moderate to excellent yields, and the reaction also showed tolerance toward functional groups such as hydro, methoxy, diethylamino, nitro, and chloro groups.

  • Synthesis of Coumarins in a Moltenn-Bu4NOAc/n-Bu4NBr Mixture through a Domino Heck Reaction/Cyclization Process
    作者:Gianfranco Battistuzzi、Sandro Cacchi、Ilse De?Salve、Giancarlo Fabrizi、Luca?M. Parisi
    DOI:10.1002/adsc.200404297
    日期:2005.2
    4-Arylcoumarins can be prepared in good to high yields by reacting readily available methyl or butyl 3-(o-hydroxyaryl)acrylates with aryl iodides and bromides in an n-Bu4NOAc/n-Bu4NBr mixture at 100 °C in the presence of Pd(OAc)2.

  • Synthesis of 4-Arylcoumarins via Cu-Catalyzed Hydroarylation with Arylboronic Acids
    作者:Yoshihiko Yamamoto、Naohiro Kirai
    DOI:10.1021/ol802239n
    日期:2008.12.18
    In the presence of 2-4 mol % of CuOAc, methyl phenylpropiolates having a MOM-protected hydroxy group at the ortho position underwent hydroarylation with various arylboronic acids in MeOH at ambient temperature, resulting in the formation of 4-arylcoumarins in high yields after the acidic workup. This method was effectively used for the synthesis of biologically active natural and artificial compounds.
  • Pd-catalyzed chemo-selective mono-arylations and bis-arylations of functionalized 4-chlorocoumarins with triarylbismuths as threefold arylating reagents
    作者:Maddali L.N. Rao、Abhijeet Kumar
    DOI:10.1016/j.tet.2014.07.059
    日期:2014.9
    4-chlorocoumarins were studied under palladium catalysis using triarylbismuths as threefold arylating reagents. The high reactivity of 4-chlorocoumarins was demonstrated delivering mono- and bis-arylation products in a chemo-selective manner. The reaction conditions employed are simple, robust and the threefold coupling reactivity of triarylbismuth reagents was witnessed with good to high yields in 2–4 h conditions
