(1a, b) and isobatzellines A and B (2a, b) are 1,3,4,5-tetrahydropyrrolo[4,3,2-de]quinoline-containing marine alkaloids characterized by the presence of a methylthio substituent at C-2 of the tricyclic system. We describe here the total synthesis of these natural compounds following the synthetic strategy that we have used previously for the synthesis of damirones A and B, batzelline C, isobatzelline
Batzellines A 和 B (1a, b) 和 isobatzellines A 和 B (2a, b) 是含有 1,3,4,5-四氢吡咯并[4,3,2-de]喹啉的海洋生物碱,其特征在于存在甲硫基三环系统的C-2上的取代基。我们在此描述了这些天然化合物的全合成,其遵循我们之前用于合成达米罗酮 A 和 B、batzelline C、isobatzelline C、discorhabdin C 和 makaluvamines A、B、C 和 D 的合成策略。通过适当取代并处于合适氧化态的吡咯并[4,3,2-脱]喹啉的亲电取代来合成甲硫基是这些合成成功的关键步骤。
