Studies towards the total synthesis of the complex diterpene spirovibsanin A are herein presented, which culminate in an 18-step total synthesis. Considering the perceived stereochemical uncertainty surrounding the assignment of spirovibsanin A these studies have allowed a direct spectroscopic comparison of the (±)-5,14-bis-epi derivative to that of natural spirovibsanin A demonstrating that the carbon
本文介绍了对复合二萜 spirovibsanin A 全合成的研究,该研究在 18 步全合成中达到高潮。考虑到围绕 spirovibsanin A 分配的立体化学不确定性,这些研究允许将 (±)-5,14-bis-epi 衍生物与天然 spirovibsanin A 的衍生物进行直接光谱比较,证明碳骨架和立体化学分配给天然 spirovibsanin A 很可能是正确的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
