The convergent synthesis of a fullyelaborated C13–C27 fragment of madeirolide A has been achieved. The key features of the synthesis include the stereocontrolled construction of both the THF and THP rings via visible-light-induced iridium-catalyzed radical cyclization and the late-stage union of the two oxacyclic subunits through nickel-catalyzed decarboxylative cross-coupling.
已经实现了马黛罗内酯 A 的完全精细 C13-C27 片段的收敛合成。该合成的关键特征包括通过可见光诱导的铱催化自由基环化立体控制构建THF和THP环,以及通过镍催化脱羧交叉偶联实现两个氧杂环亚基的后期结合。
