  • Quinine-catalyzed highly enantioselective cycloannulation of o-quinone methides with malononitrile

    2-Amino-3-cyano-4H-chromenes show great potential as novel anticancer agents. Here we report a quinine-catalyzed highly enantioselective formal 4 + 2 cycloaddition of ortho-quinone methides and malononitrile, providing a unique approach to 4-arylvinyl, 4-aryl and 4-vinyl 2-amino-3-cyano-4H-chromenes with excellent yields and enantioselectivities.

  • A New Synthesis of<i>o</i>-Quinonemethides and Their Inter- and Intramolecular Cyclization Reactions
    作者:Tsutomu Inoue、Seiichi Inoue、Kikumasa Sato
    DOI:10.1246/bcsj.63.1062
    日期:1990.4
    The reaction of o-[1-(alkylthio)alkyl]phenols with silver(I) oxide at room temperature generated o-quinonemethides in good yields along with silver alkanethiolate. This mechanism, based upon one-electron oxidation, is excluded in view of several experimental facts. The resulting o-quinonemethides reacted efficiently with ethyl vinyl ether to afford cis-chromans as the result of endo cycloaddition between (E)-o-quinonemethides and the ether. Similarly, o-[1-(alkylthio)allyl]phenols were converted to cis-chromans via the corresponding (E)-o-quinonemethides (6-allylidenecyclohexadienone). In the absence of dienophiles, some chromenes were obtained from the allylphenols.
    室温下,o-[1-(烷硫基)烷基]苯酚与氧化银反应,能以良好产率生成邻醒甲叉中间体和银的烷硫醇盐。根据几个实验事实,基于单电子氧化的机制被排除。生成的邻醒甲叉中间体能高效地与乙基乙烯基醚反应,通过邻醒甲叉中间体与醚的endo环加成反应,生成顺式色满。类似地,o-[1-(烷硫基)烯丙基]苯酚通过相应的邻醒甲叉中间体(6-烯丙叉环己二烯酮)转化为顺式色满。在没有双烯亲和物存在时,从烯丙基苯酚获得了一些色烯。

    synthesized by the intermolecular cycloaddition reaction of terpenes and o-quinone methides generated in situ by electrochemical oxidation. In a two-phase reaction medium composed of hexane-lithium perchlorate/nitromethane, 2-[1-(propylsulfanyl)alkyl]phenols were selectively oxidized to give the corresponding unstable o-quinone methides. These intermediates were trapped in situ by unactivated alkenes or easily
    通过萜烯与通过电化学氧化原位生成的邻醌甲基化物的分子间环加成反应合成了Euglobal骨架。在由己烷-高氯酸锂/硝基甲烷组成的两相反应介质中,将2- [1-(丙基硫烷基)烷基]酚选择性氧化,得到相应的不稳定的邻醌甲基化物。这些中间体被未活化的烯烃或易氧化的萜烯原位捕获,形成各种色度和螺色度,包括真球形。特别是,在β蒎烯的存在下,蓝桉醛II b骨架,其具有一个β水芹烯基部分,通过环加成形成经由 β-pine烯的骨架重排。
  • Enantioselective Addition of Boronates to <i>o</i>-Quinone Methides Catalyzed by Chiral Biphenols
    作者:Yi Luan、Scott E. Schaus
    DOI:10.1021/ja309076g
    日期:2012.12.12
    Chiral biphenols were found to catalyze the enantioselective asymmetric addition of aryl- or alkenylboronates to o-quinone methides. Substituted 2-styryl phenols were obtained in good yields (up to 95%) with high enantiomeric ratios (up to 98:2) in the presence of 10 mol % 3,3'-Br(2)-BINOL. A two-step synthesis of (S)-4-methoxydalbergione in good yield and selectivity was achieved.
