[reaction: see text] A short synthesis of intermediates possessing the tricyclic core of natural madangamines, bioactive alkaloids found in marine sponges, is described. The key reaction entails the condensation of the sodium salt of diethylacetonedicarboxylate with a dihydropyridinium salt derivative. This new approach is modeled on a biogenetic proposal linking madangamines to ircinals, related alkaloids
[反应:见正文]描述了一种简短合成的中间体,该中间体具有天然madangamines的三环核心,即海洋海绵中发现的生物活性生物碱。关键反应需要使二乙基丙酮二羧酸钠盐与二氢吡啶鎓盐衍生物缩合。这种新方法是基于将麦当胺与ircinals(一种在相同数量的海绵中存在的相关生物碱)相关联的生物遗传学提案进行建模的。
