1,6-conjugate arylation of 2-(aryl)-phenyl-substituted p-quinone methides (QMs) under continuous flow using the microreaction technique. This method was found to be very effective for most of the p-QMs, and the corresponding 9-aryl fluorene derivatives were obtained in moderate to excellent yields. Moreover, this protocol was further elaborated to the first total syntheses of selaginpulvilin I and isoselagintamarlin
在本文中,我们描述了一种通过 TfOH 催化的 2-(芳基)-苯基取代的对醌甲基化物 (QM) 的分子内 1,6-共轭芳基化在连续流动下使用9-芳基芴衍生物的便捷方法。微反应技术。发现该方法对大多数p -QM非常有效,并且以中等至优异的产率获得了相应的 9-芳基芴衍生物。此外,该方案进一步阐述了selaginpulvilin I和isoselagintamarlin A的首次全合成。
