The isolation of flueggenines A and B by Yue and co-workers in 2006 has triggered a burst of isolation reports of dimeric and oligomeric securinega alkaloid natural products. The compelling molecular structures of these compounds with various modes of connection between monomeric securinega units have posed intriguing challenges to the synthetic organic community. Herein, we have categorized high-order securinega alkaloids based on their biosynthetic mode of dimerization or oligomerization. We then have compiled all reported syntheses of dimeric securinega alkaloids based on our classification. 1 Introduction 2 Categorization of High-Order Securinega Alkaloid Natural Products 3 Syntheses of Type I Dimeric Securinega Alkaloids 4 Syntheses of Type II Dimeric Securinega Alkaloids 5 Synthesis of Type III Dimeric Securinega Alkaloid 6 Conclusion

二聚叶鞘生物碱的合成

2006 年Yue 等人对氟草碱A 和B 的分离引发了一波二聚和寡聚叶鞘生物碱天然产物的分离报道。这些化合物的引人注目的分子结构与单体 securinega 单元之间的各种连接模式给合成有机群落带来了有趣的挑战。在此，我们根据二聚或寡聚的生物合成模式对高阶叶底生物碱进行了分类。然后，我们根据我们的分类汇编了所有报道的二聚叶鞘生物碱合成。1 引言 2 高阶叶柄生物碱天然产物的分类 3 I 型二聚叶基亚生物碱的合成 4 II 型二聚叶基亚生物碱的合成 5 III 型二聚叶基亚生物碱的合成 6 结论
