  • A General Synthesis of Alkenyl‐Substituted Benzofurans, Indoles, and Isoquinolones by Cascade Palladium‐Catalyzed Heterocyclization/Oxidative Heck Coupling
    作者:Rosana Álvarez、Claudio Martínez、Youssef Madich、J. Gabriel Denis、José M. Aurrecoechea、Ángel R. de Lera

    日期:2010.11.8
    consecutive Sonogashira and cascade Pd‐catalyzed heterocyclization/oxidative Heck couplings from readily available ortho‐iodosubstituted phenol, aniline, and benzamide substrates, alkynes, and functionalized olefins. The cyclization of O‐ and N‐heteronucleophiles follows regioselective 5‐endo‐dig‐ or 6‐endo‐dig‐cyclization modes, whereas the subsequent Heck‐type coupling with both mono‐ and disubstituted
    通过使用连续的Sonogashira和级联的Pd催化的杂环/氧化Heck偶联反应,可以容易地从邻位碘取代的苯酚,苯胺和苯甲酰胺和苯甲酰胺底物,炔烃和官能化的烯烃中高效地制备结构多样的C3-烯基苯并呋喃,C3-烯基吲哚和C4-烯基异喹啉酮。。O-和N- heteronucleophiles的环化如下区域选择性5-内切-挖-或6-内-挖-cyclization模式,而用两个单和二取代的烯烃随后的Heck型偶联发生立体选择性地与所述的只形成ë大多数情况下是异构体。
  • Palladium-Catalyzed Sequential Oxidative Cyclization/Coupling of 2-Alkynylphenols and Alkenes: A Direct Entry into 3-Alkenylbenzofurans
    作者:Claudio Martínez、Rosana Álvarez、José M. Aurrecoechea
    DOI:10.1021/ol8028687
    日期:2009.3.5
    A now Pd-catalyzed tandem Intramolecular oxypalladation/Heck-type coupling between 2-alkynylphenols and alkenes Is reported, leading to 3-(1-alkenyl)benzofurans. Participating alkenes include those substituted with an electron-withdrawing group (ester, ketone, amide, nitrile, sulfone), as well as styrene. Remarkably, beta-substituted-alpha,beta-unsaturated carbonyl-type derivatives also participate effectively. The ready availability of substituted alkynylphenols, together with flexibility in the alkene choice, makes this simple strategy a versatile one for the synthesis of structurally diverse benzofuran derivatives.
