The first total synthesis of talaroconvolutin A (1.1 g obtained) and talarofuranone has been achieved using accessible materials (12 steps, 7.5% and 8.2% yields, respectively). Convergent routes involved intramolecular Diels−Alder reactions in two approaches for creating the decalin moiety. Additionally, an unprecedented DMP-mediated domino reaction resulted in the deoxy-tetramic acid system. These
使用可获取的材料首次实现了talaroconvolutin A(获得1.1 g)和talarofuranone的全合成(12步,产率分别为7.5%和8.2%)。收敛路线涉及分子内狄尔斯-阿尔德反应,有两种方法用于产生十氢萘部分。此外,前所未有的 DMP 介导的多米诺骨牌反应产生了脱氧四胺酸系统。这些合成不仅建立了 talaroconvolutin A 的绝对构型,而且还使得能够对此类铁死亡诱导剂进行进一步的合作研究。
