  • Alcohol Mediated Synthesis of 4-Oxo-2-aryl-4<i>H</i>-chromene-3-carboxylate Derivatives from 4-Hydroxycoumarins
    作者:Manoj R. Zanwar、Mustafa J. Raihan、Sachin D. Gawande、Veerababurao Kavala、Donala Janreddy、Chun-Wei Kuo、Ram Ambre、Ching-Fa Yao
    DOI:10.1021/jo301044y
    日期:2012.8.3
    The unusual alcohol mediated formation of 4-oxo-2-aryl-4H-chromene-3-carboxylate (flavone-3-carboxylate) derivatives from 4-hydroxycoumarins and β-nitroalkenes in an alcoholic medium is described. The transformation occurs via the in situ formation of a Michael adduct, followed by the alkoxide ion mediated rearrangement of the intermediate. The effect of the different alcohol and nonalcohol media on
    这种不寻常的醇介导的4-氧代-2-芳基-4-的形成ħ色烯-3-羧酸甲酯(黄酮-3-羧酸)衍生物由4-羟基香豆素和β-硝基烯烃在醇介质进行说明。该转化通过原位形成迈克尔加合物而发生,随后是醇盐离子介导的中间体重排。研究了不同醇和非醇介质对反应的影响。
  • Synthesis of 3-substituted carboxylate/carboxamide flavone derivatives from 4-hydroxycoumarin, β-nitrostyrene and alcohol/amine using multicomponent reaction
    作者:Suchandra Bhattacharjee、Abu T. Khan
    DOI:10.1016/j.tetlet.2016.03.026
    日期:2016.4
    A wide range of 3-substituted carboxylate/carboxamide flavone derivatives were synthesized from 4-hydroxycoumarin, β-nitrostyrene and alcohol/amine using multicomponent reaction in the presence of N,N-dimethyl-4-aminopyridine (DMAP). Good yield, short reaction time, atom economy, cost effectiveness, and use of non-toxic organo-catalyst are some of the remarkable advantages of the present protocol.
    在N,N-二甲基-4-氨基吡啶(DMAP)存在下,使用多组分反应由4-羟基香豆素,β-硝基苯乙烯和醇/胺合成了多种3-取代的羧酸盐/羧酰胺黄酮衍生物。良好的产率,短的反应时间,原子经济性,成本效益以及使用无毒有机催化剂是本方案的显着优点。
  • Construction of trisubstituted chromone skeletons carrying electron-withdrawing groups via PhIO-mediated dehydrogenation and its application to the synthesis of frutinone A
    作者:Qiao Li、Chen Zhuang、Donghua Wang、Wei Zhang、Rongxuan Jia、Fengxia Sun、Yilin Zhang、Yunfei Du
    DOI:10.3762/bjoc.15.291
    日期:——
    The construction of the biologically interesting chromone skeleton was realized by PhIO-mediated dehydrogenation of chromanones under mild conditions. Interestingly, this method also found application in the synthesis of the naturally occurring frutinone A.
    通过PhIO介导的色酮在温和条件下的脱氢作用,实现了具有生物学意义的色酮骨架的构建。有趣的是,该方法还发现了在天然存在的果丁酮A合成中的应用。
