methanoquinolizidine core have evaded synthetic efforts. We report an asymmetric approach to these alkaloids, which has culminated in the first total syntheses of (-)-2(S)-cathafoline and the long-standing target (+)-strictamine. Moreover, the first enantioselective total synthesis of aspidophylline A is described.
akuammiline
生物碱是几十年来被广泛研究的
天然产物家族。尽管最近取得了显着的合成成果,但具有甲
喹啉齐啶核心的 akuammilines 却未能实现合成努力。我们报告了对这些
生物碱的不对称方法,其在 (-)-2(S)-cathafoline 和长期存在的目标 (+)-strictamine 的首次全合成中达到高潮。此外,还描述了第一次对映选择性全合成 aspidophylline A。
