  • Stille coupling for the synthesis of isoflavones by a reusable palladium catalyst in water
    作者:Ya‐Ting Chang、Ling‐Jun Liu、Wen‐Sheng Peng、Lin‐Ting Lin、Yi‐Tsu Chan、Fu‐Yu Tsai
    DOI:10.1002/jccs.202000478
    日期:2021.3
    Isoflavones were synthesized from the reaction of 3‐bromochromone derivatives and aryltributylstannanes via Stille coupling catalyzed by a water‐soluble and reusable PdCl2(NH3)2/2,2′‐cationic bipyridyl system in aqueous solution. For prototype 3‐bromochromone, the coupling reaction was performed at 80°C for 24 hr with 2.5 mol% catalyst in water in the presence of tetrabutylammonium fluoride. After
    黄酮是通过溶性可重用的PdCl 2(NH 3)2 / 2,2'-阳离子联吡啶系统在溶液中催化的Stille偶联反应,由3-溴色酮生物与芳基三丁基锡烷反应制得的。对于原型3-溴苯并二氢呋喃酮,偶合反应是在化四丁基存在下,在中使用2.5 mol%催化剂,在80°C下进行24小时。反应后,该溶液可重复使用几次,表明其活性仅略有下降。对于取代的3-溴色酮,添加NaHCO 3需要较高的反应温度(120°C)才能获得满意的结果。此外,该方案可通过一锅反应获得天然产物,如黄豆苷元。
  • Arylation of <i>ortho</i>-Hydroxyarylenaminones by Sulfonium Salts and Arenesulfonyl Chlorides: An Access to Isoflavones
    作者:Satenik Mkrtchyan、Viktor O. Iaroshenko
    DOI:10.1021/acs.joc.0c02294
    日期:2021.4.2
    diversities of bench-stable and easy-to-use sulfonium salts and arenesulfonyl chlorides. Both developed methods, namely the light-mediated photoredox and electrophilic arylation, showed good efficiency, and are feasible for the preparation of 3-arylchromones in good-to-excellent yields. This work showcases the first described attempt where the sulfonium salts and arenesulfonyl chlorides were successfully utilized
    本文中,我们公开了三种新方法,这些方法可通过大量稳定和易于使用的sulf盐和芳烃磺酰氯将邻羟基羟基亚胺基芳基化后,直接有效地合成3-芳基色酮。两种开发的方法,即光介导的光氧化还原和亲电芳基化,均显示出良好的效率,并且对于以良好至优异的产率制备3-芳基色酮是可行的。这项工作展示了首次描述的尝试,其中成功地利用了salts盐和芳烃磺酰氯来构建色酮杂环系统。

    DOI:10.1055/s-0029-1217959
    日期:2009.10
    An efficient cross-coupling of 3-iodochromones with triarylbismuths under catalytic palladium conditions is reported. Triarylbismuths were employed as substoichiometric multicoupling nucleophiles for the synthesis of a variety of substituted isoflavones. Under the established protocol, cross-coupling reactions were found to be very efficient, furnishing high yields of products.
