  Robustaflavone, intermediates and analogues and method for preparation thereof

  摘要：

  本文提供了Robustaflavone、其中间体和类似物的合成方法。该方法涉及构建含有6位和3'位官能团的黄烷酮醚，可以使用过渡金属催化交叉偶联。该方法还涉及开发一种在6位上碘化黄烷酮衍生物的区域选择性碘化方法，使用钯催化将相应的3'位碘化物与二硼试剂交换形成黄烷酮3'硼酸酯。最后，使用Suzuki偶联反应形成Robustaflavone的立体阻碍的6-3'双芳基键，从而获得所需的双黄烷类系统。Robustaflavone中间体和类似物可用于制备其他双黄烷类化合物的类似物，如hinokifavone、rhusflavone和succedaneaflavone。
