  • The Discovery of a Novel Route to Highly Substituted α-Tropolones Enables Expedient Entry to the Core of the Gukulenins
    作者:Roman Kats-Kagan、Seth B. Herzon
    DOI:10.1021/acs.orglett.5b00841
    日期:2015.4.17
    A simple and general method for the synthesis of highly substituted α-tropolone ethers that allows rapid access to the bis(tropolone) core of the antiproliferative metabolites (−)-gukulenins A and F (3, 4) is described. The reaction proceeds by thermolytic opening of gem-dibromobicyclo[4.1.0]heptane intermediates, which are readily accessed from simple starting materials. Mechanistic studies suggest

  • Intermolecular Diels−Alder Reactions of Brominated Masked <i>o</i>-Benzoquinones with Electron-Deficient Dienophiles. A Detour Method to Synthesize Bicyclo[2.2.2]octenones from 2-Methoxyphenols
    作者:Chien-Hsun Lai、Yi-Ling Shen、Min-Nen Wang、N. S. Kameswara Rao、Chun-Chen Liao

    日期:2002.9.1
    Intermolecular Diels-Alder reactions of masked o-benzoquinones, i.e., 6,6-dimethoxy-2,4-cyclohexadienones 5-7 and 21-24 generated from 2-methoxyphenols 1-3 and 17-20, respectively, with electron-deficient dienophiles leading to highly functionalized bicyclo[2.2.2]octenones are described. The masked o-benzoquinones (MOBs) 5-7 underwent Diels-Alder cycloadditions with methyl acrylate, methyl methacrylate
    掩蔽的邻苯甲醌的分子间狄尔斯-阿尔德反应,即分别由2-甲氧基苯酚1-3和17-20生成的6,6-二甲氧基-2,4-环己二酮5-7和21-24,具有电子缺陷描述了导致高度官能化的双环[2.2.2]辛烯酮的亲二烯体。用丙烯酸甲酯,甲基丙烯酸甲酯和甲基乙烯基酮对被掩盖的邻苯醌(MOBs)5-7进行狄尔斯-阿尔德环加成反应,从而以低至产量适中,伴随形成大量的二聚体9-11。为了延迟二聚作用并提高必需的双环[2.2.2]辛烯酮的产率,已经开发了一种tour回方法,其包括2-甲氧基苯酚1-4的顺序溴化,氧化和Diels-Alder反应以及脱溴。溴酚17-20的氧化产生的MOB 21-24足够稳定,可以分离出来。使MOB 21-24与缺电子的亲二烯体以非常有效的方式进行环加成反应,以高产率至高产率提供相应的环加合物25a-c至28a-c,而无需自我二聚。当用Bu(3)SnH / AlBN或甲酸三丁铵甲酸
  • Substituent effect on di-π-methane reactions of benzopyrazinobarrelenes and benzoquinoxalinobarrelenes
    作者:Gary J. Chuang、Chun-Chen Liao
    DOI:10.1016/j.tet.2016.01.021
    日期:2016.3
    To examine the substituent effect on the di-π-methane (DPM) rearrangement of barrelene-like skeleton, benzopyrazinobarrelene (BPB) and benzoquinoxalinobarrelene (BQB) were utilized as the photoreaction experimental platforms. By the installation of the pyrazine, the DPM reaction was limited to aza-di-π-methane reaction only, in terms of chemoselectivity. The results of the induced regioselectivity
    为了检查取代基对桶状骨架的二π-甲烷(DPM)重排的影响,将苯并吡嗪并戊烯酮(BPB)和苯并喹喔啉并戊烯酮(BQB)用作光反应实验平台。通过安装吡嗪,就化学选择性而言,DPM反应仅限于氮杂-二-π-甲烷反应。检查了诱导的BPM和BQB的DPM重排的区域选择性的结果,该BPB和BQB具有连接到烯烃/桥头位置的多种不同取代基。
