The concise and enantioselective totalsyntheses of (-)-trigonoliimines A, B, and C are described. Our unified strategy to all three natural products is based on asymmetric oxidation and reorganization of a single bistryptamine, a sequence of transformations with possible biogenetic relevance. We revise the absolute stereochemistry of (-)-trigonoliimines A, B, and C.
描述了 (-)-trigonoliimines A、B 和 C 的简洁和对映选择性全合成。我们对所有三种天然产物的统一策略是基于单个双色胺的不对称氧化和重组,这是一系列可能具有生物遗传相关性的转化。我们修改了 (-)-trigonoliimine A、B 和 C 的绝对立体化学。

A full account of our concise and enantioselective total syntheses of all known (−)-trigonoliimine alkaloids is described. Our retrobiosynthetic analysis of these natural products enabled identification of a single bistryptamine precursor as a precursor to all known trigonoliimines through a sequence of transformations involving asymmetric oxidation and reorganization. Our enantioselective syntheses
描述了我们对所有已知 (-)-trigonoliimine 生物碱的简洁和对映选择性全合成的完整说明。我们对这些天然产物的逆生物合成分析能够通过一系列涉及不对称氧化和重组的转化,鉴定出一种单一的双色胺前体作为所有已知葫芦亚胺的前体。我们对这些生物碱的对映选择性合成能够修正 (-)-trigonoliimines A、B 和 C 的绝对立体化学。我们报告说,trigonoliimines A、B、C 和结构相关的化合物对 HeLa 和 U-937 细胞显示出较弱的抗癌活性.
