  • Synthesis of Isocoumarin via PTSA-Catalyzed Annulation of Diarylalkynes

    日期:2008.5
    p-Toluenesulfonic acid (PTSA) in ethanol was used as a mild acid catalyst for the annulation of various functionalized diarylalkynes under microwave irradiation. This metal-free process allowed the synthesis of a range of 3-aryl-substituted isocoumarins in good yields.

    cascade reaction of internal alkynols with 1-(2-aminophenyl)prop-2-ynols has been developed to form a new N,O-containing fused 5,5,6-tricyclic skeleton. Mechanistic studies indicate that this reaction proceeds via alkynol cycloisomerization, intermolecular substitution with 1-(2-aminophenyl)prop-2-ynols, conjugated addition with alkynols and consequent cyclizations. In this way, two C-C bonds, one C-O
    已开发出内部炔醇与1-(2-氨基苯基)丙-2-炔醇的新型级联反应,以形成新的含N,O的稠合5,5,6-三环骨架。机理研究表明,该反应通过炔醇环异构化,用1-(2-氨基苯基)丙-2-炔醇的分子间取代,与炔醇的共轭加成以及随后的环化而进行。通过这种方式,两个CC键,一个CO键和一个CN键形成一个环,从而在一个反应​​中形成三环骨架。
  • Tf2O/TfOH catalytic glycosylation using o-(p-methoxyphenylethynyl)benzyl glycosides as donors and its application in synthesis of oligosaccharides

    日期:2023.2
    A catalytic glycosylation protocol was established using Tf2O or TfOH as catalyst and o-(p-methoxyphenylethynyl)benzyl (MPEB) glycosides as donors. The MPEB donors are stable and readily prepared from inexpensive starting material. The donors were activated by 10 mol% Tf2O or TfOH and coupled with various acceptors to provide desired glycosides in modest to good yield. This glycosylation protocol was

    1H-Isochromenes and 1,2-dihydroisoquinolines are synthesized by regioselective indium(III)-catalyzed intramolecular hydrofunctionalization of o-(alkynyl)benzyl derivatives. The reaction with o-(alkynyl)benzyl alcohols and amines proceeds using indium triiodide (5–10 mol%) in toluene at 80–100 °C via regioselective 6-endo-dig intramolecular alkyne hydroalkoxylation or hydroamination in good yields.
    1H-Isochromene 和 1,2-dihydroisoquinolines 是通过区域选择性铟 (III) 催化的 o-(炔基) 苄基衍生物的分子内氢官能化合成的。在 80–100 °C 下,在甲苯中使用三碘化铟 (5–10 mol%),通过区域选择性 6-内切-分子内炔烃加氢烷氧基化或加氢胺化,以良好的产率与邻(炔基)苄醇和胺进行反应。或者,在较温和的反应条件下,使用 InI3 (5 mol%) 和 Hantzsch 酯 (120 mol%) 发生 o-(炔基) 苯甲醛和亚胺衍生物的环异构化反应,得到各种功能化的 1H-异色烯和 1 ,2-二氢异喹啉通过多米诺环异构化/还原方法。
  • Synthesis of Functionalized 1<i>H</i>-Isochromene Derivatives via a Au-Catalyzed Domino Cycloisomerization/Reduction Approach
    作者:Eder Tomás-Mendivil、Jérôme Starck、Jean-Claude Ortuno、Véronique Michelet
    DOI:10.1021/acs.orglett.5b03146
    日期:2015.12.18
    A Au-catalyzed versatile and efficient access to 1H-isochromenes is reported. The efficiency of the [AuCl2(Pic)] complex (15 mol %) was demonstrated and allowed a domino cycloisomerization/reduction reaction process starting from a wide range of functionalized ortho-alkynylbenzaldehydes and one example of ortho-alkynylpyridinylaldehyde. The smooth reaction conditions were amenable to aryl- and alkyl-substituted alkynyl derivatives, as well as functionalized halogen and ether moieties, leading to a chemo- and regioselective 6-endo-cyclization with good to excellent yields.
