    摘要:
    报道了在没有光催化剂的情况下,从 3-芳基乙炔香豆素温和有效的可见光诱导合成 C-3 二羰基香豆素。这种碘化物介导的方法具有广泛的底物范围和良好的官能团耐受性,并以中等至优异的收率获得了一系列 C-3 二羰基香豆素。基于对照实验结果,发现可见光诱导的氧化可能是通过自由基和离子过程。此外,一些合成化合物对过氧化氢 (H 2 O 2 )显示出高灵敏度,检测限低(DL,低至 0.149 μM)。

  • Aqueous Ammonia as a New Activator for Sonogashira Coupling
    作者:Mohamed S. Mohamed Ahmed、Akitoshi Sekiguchi、Kentaro Masui、Atsunori Mori
    DOI:10.1246/bcsj.78.160
    日期:2005.1
    Sonogashira coupling, which is a coupling reaction of terminal alkynes with organic halides, takes place with dilute aqueous ammonia as an activator. The reaction of several terminal alkynes and aryl iodides in the presence of small excess of aqueous ammonia at room temperature furnishes the cross-coupling product in good-to-excellent yields. A water-soluble amine with a high boiling point is alternatively employed for reactions at higher temperatures. A related coupling reaction in the presence of carbon monoxide also proceeded at room temperature and under ambient pressure to afford α,β-alkynyl ketones efficiently.
    Sonogashira偶联反应,是一种端炔与有机卤化物的偶联反应,在稀释的氨水溶液中作为活化剂的情况下进行。在室温下,少量过量的氨水存在时,几种端炔与芳基的反应能以良好的至极佳的产率得到交叉偶联产物。另一种选择是在较高温度下的反应中使用高沸点的溶性胺。类似的在二氧化碳存在下的偶联反应也能在室温和常压下高效地进行,生成α,β-炔基酮。

    DOI:10.1246/cl.2002.756
    日期:2002.7
    The coupling reaction of terminal alkynes with organic halides, Sonogashira-(Hagihara) coupling, takes place with only 2 equivalents of dilute aqueous ammonia as an additive. The reaction of phenylacetylene and 4-iodoanisole in the presence of 1 mol% of PdCl2(PPh3)2, 2 mol% of CuI, and 2 equiv of aqueous ammonia in THF proceeds at room temperature for 6 h to afford the coupling product in a quantitative yield.

  • Synthesis and Electrogenerated Chemiluminescence of Donor-Substituted Phenylethynylcoumarins
    作者:Arumugasamy Elangovan、Jui-Hsien Lin、Shu-Wen Yang、Hsien-Yi Hsu、Tong-Ing Ho
    DOI:10.1021/jo0493424
    日期:2004.11.1
    Two series of donor-bearing phenylethynylcoumarins have been synthesized, and their photophysical properties have been evaluated. Chemiluminescence was observed through the annihilation of their electrogenerated radical ions and was found to be only slightly affected by the presence of various donor groups on the phenyl moiety linked through the C-C triple bond. The overall properties of the two series of compounds are discussed with respect to their structures. The observed electronic absorption properties are explained with the help of computational studies.
