7,8-Diarylflavones were prepared by Suzuki-Miyaura reactions of the bis(triflate) of 7,8-dihydroxyflavone. The first attack proceeded with very good site selectivity at position 7, due to steric and electronic reasons.
7,8-二芳基
黄酮是通过
7,8-二羟基黄酮的双(
三氟甲磺酸酯)的 Suzuki-Miyaura 反应制备的。由于空间和电子原因,第一次攻击在位置 7 处具有非常好的位点选择性。
