The first total synthesis of the fungal pyrroloquinoline alkaloids mycenarubin A, sanguinolentaquinone and mycenaflavin B are reported. Key steps for the synthesis of mycenarubin A are an enantioselective alkylation and biomimetic Michael addition, and for mycenaflavin B, biomimetic ring closure and acidic decarboxylation. The cytotoxicities of mycenarubin A and mycenaflavin B have been evaluated.
报道了真菌吡咯并喹啉生物碱mycenarubin A,sanguinolentaquinone和mycenaflavin B的第一个全合成。合成Mycenarubin A的关键步骤是对映选择性烷基化和仿生Michael加成反应,而Mycenaflavin B合成的关键步骤是仿生闭环和酸性脱羧反应。已经评估了mycenarubin A和mycenaflavin B的细胞毒性。
