Abstract

Zyzzyanones A–D is a group of biologically active marine alkaloids isolated from Australian marine sponge Zyzzya fuliginosa. They contain a unique bispyrroloquinone ring system as the core structure. The first total synthesis of all four zyzzyanones is described here. The synthesis of these alkaloids started from a previously known 6-benzylamino indole-4, 7- quinone derivative and involves 6–7 steps. The key step in the synthesis involves the ...
