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.
