Eudistomins L, K, C, E (30) and F (33) were synthesized from the corresponding N-hydroxytryptamine 21 and the D-cysteinal 23. A bromine of eudistomin L was biomimetically introduced onto the pyrroloindolic intermediate 8. Other eudistomins were prepared from substituted indoles 17. A modified Pummerer reaction was used to obtain the oxathiazepine ring.
由相应的N-羟色胺21和D-半胱氨酸23合成Eudistomin L、K、C、E(30)和F(33)。将eudistomin L的溴仿生引入到吡咯吲哚中间体8上。制备其他eudistomin由取代的吲哚 17 生成。使用改进的 Pummerer 反应获得氧硫氮杂环。
