The application of cyclic diaryliodonium salts in the synthesis of bioactive natural product analogues was demonstrated. Axially chiral biaryls were obtained via the enantioselective ring opening of cyclic diaryliodonium salts. Regioselective borylation was key in accessing both enantiomers of a biphenol key intermediate in eight steps overall. 8,8″-Amino biflavones were synthesized, their bioactivity
展示了环状二芳基碘鎓盐在生物活性天然产物类似物合成中的应用。轴向手性联芳基是通过环状二芳基碘鎓盐的对映选择性开环获得的。区域选择性硼化是通过八个步骤获得联苯酚关键中间体的两种对映体的关键。合成了 8,8”-氨基双黄酮,分析了其生物活性,并鉴定了优异构体。探讨了结构-活性关系。
