The total syntheses of the natural product 3-O-methylfunicone (1), a member of the funicone class of compounds, and its derivatives is reported. The key reactions in the construction of the biaryl ketone core are a regioselective TMPZnCl·LiCl halogenation and a carbonylative Stille cross-coupling reaction. In addition, the inhibitory activities of the funicones against Y-family DNA polymerase κ (pol
报告了天然产物 3-O-methylfunicone (1) 的全合成,它是 funicone 类化合物的一个成员,及其衍生物。联芳基酮核构建的关键反应是区域选择性TMPZnCl·LiCl卤化和羰基化Stille交叉偶联反应。此外,还测定了锥体对 Y 家族 DNA 聚合酶 κ (pol κ) 和聚合酶 η (pol η) 的抑制活性。我们发现 1 和 12 对 pol η 表现出抑制活性,1 也对 pol κ 表现出抑制活性。
