Abstract The asymmetric synthesis of 16,17,20-epi-deserpidine and a derivative of (–)-deserpidine has been achieved. Key features in the assembly of the pentacyclic framework include a visible-light photocatalytic intra-/inter-/intramolecular radical cascade reaction to construct the tetracyclic ABCD ring system in one-pot and an intramolecularaldol reaction to forge the cyclohexane E ring.
摘要实现了16,17,20-表-二萜和(-)-二萜的衍生物的不对称合成。五环骨架组装的关键特征包括:可见光光催化内/间/分子内自由基级联反应,以一锅构建四环ABCD环系统;分子内醇醛反应,以锻造环己烷E环。
