  • 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。
  • Hypervalent Iodine Oxidation of Flavanones: A New Synthesis of Methyl 2-Aryl-2,3-dihydrobenzofuran-3-carboxylates by 1,2-Aryl Shift
    作者:Om Prakash、Madan P. Tanwar
    DOI:10.1246/bcsj.68.1168
    日期:1995.4
    Flavanones (1), on oxidation with (diacetoxyiodo)benzene-sulfuric acid (DIB–H2SO4) or (hydroxy)tosyloxy)iodo)benzene (HTIB) in trimethyl orthoformate, undergo facile ring contraction by 1,2-aryl shift, thereby yielding methyl 2-aryl-2,3-dihydrobenzofuran-3-carboxylates (4) as major products (40—80%). cis-3-Methoxyflavanones (5) and flavones (3) are the minor products formed in variable ratios.
    黄烷酮 (1) 在用原甲酸三甲酯中的(二乙酰氧基)苯-硫酸(DIB–H2SO4)或(羟基)甲苯磺酰氧基))苯(HTIB)氧化时,通过 1,2-芳基位移发生容易的环收缩,从而产生2-芳基-2,3-二氢苯并呋喃-3-羧酸甲酯 (4) 作为主要产物 (40-80%)。顺式 3-甲氧基黄烷酮 (5) 和黄酮 (3) 是以可变比例形成的次要产物。
  • Oxidative 1,2-aryl rearrangement in flavanones using thallium(III) -tolylsulphonate (TTS)= A new useful route to isoflavones
    作者:Om V. Singh、C.P. Garg、R.P. Kapoor
    DOI:10.1016/s0040-4039(00)94689-6
    日期:1990.1
    Oxidation of flavanones using thallium(III) -tolylsulphonate (prepared by the reaction of thallium(III) acetate and -toluene sulphonic acid) in propionitrile leads to 1,2-aryl shift providing a new useful route to the synthesis of isoflavones.
    丙腈中使用甲苯磺酸th (III)(由乙酸III(III)和-甲苯磺酸反应制得)对黄烷酮进行氧化可导致1,2-芳基转移,为异黄酮的合成提供了一条新的有用途径。
  • Pd-Catalyzed Efficient Cross-Couplings of 3-Iodochromones with Triaryl­bismuths as Substoichiometric Multicoupling Organometallic Nucleophiles
    作者:Maddali Rao、Varadhachari Venkatesh、Deepak Jadhav
    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.
    报告了在催化条件下 3-色酮与三芳基的高效交叉偶联。三芳基被用作亚公倍数多偶联亲核物,用于合成多种取代的异黄酮。在既定的方案下,交叉耦合反应非常有效,产物收率高。
  • Synthesis, antimycobacterial evaluation and pharmacophore modeling of analogues of the natural product formononetin
    作者:Peggoty Mutai、Elumalai Pavadai、Ian Wiid、Andile Ngwane、Bienyameen Baker、Kelly Chibale
    DOI:10.1016/j.bmcl.2015.04.064
    日期:2015.6
    The synthesis and antimycobacterial activity of formononetin analogues is hereby reported. Formononetin and its analogue 11E showed 88% and 95% growth inhibition, respectively, against the H37Rv strain of Mycobacterium tuberculosis. Pharmacophore modeling studies indicated that the presence of a hydroxyl group in formononetin and its analogues, is crucial for maintaining activity. (C) 2015 Elsevier Ltd. All rights reserved.
