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。

An unprecedented deconstructive reorganization strategy for the denovosynthesis of hydroxylated benzofurans from kojic acid- or maltol-derived alkynes is reported. In this reaction, both the benzene and furan rings were simultaneously constructed, whereas the pyrone moiety of the kojic acid or maltol was deconstructed and then reorganized into the benzene ring as a six-carbon component. Through this
Deoxyfunicone, rapicone and their 5,6-epoxy-derivatives are gamma-pyrone compounds with cytostatic and antiproliferative properties. Here we describe a synthesis of these compounds by carbonylative Stille coupling between kojic acid derivatives and functionalized iodo aryl compounds. The main advantages of this patent pending synthetic strategy lie in the simplicity and clean conversion of products, and in the possibility to obtain a high number of analogs by minor changes of the synthetic synthons.
