A total synthesis of ammosamideB, a metabolite of the marine-derived Streptomyces strain CNR-698, has been executed in nine steps and 6.9% overall yield. The key step involves the condensation of a 4,6-diBoc-protected 1,3,4,6-tetraaminobenzene derivative with dimethyl 2-ketoglutaconate, which effectively constructs the pyrrolidinone ring and the quinoline ring in a single step. This contributes a
氨酰胺 B 是海洋来源的链霉菌属菌株 CNR-698的代谢物,已分九步完成,总产率为 6.9%。关键步骤涉及 4,6-diBoc 保护的 1,3,4,6-四氨基苯衍生物与 2-酮戊二酸二甲酯的缩合,这一步有效地构建了吡咯烷酮环和喹啉环。这为吡咯并喹啉生物碱的合成提供了一种独特的方法,该方法具有简洁性和相对较高的总收率的优点。
