Significance

Azaspiracid-1 is isolated from mussels (Mytilus edulis). It causes nausea, vomiting and diarrhea with damage to the liver and spleen and it induces the formation of lung tumors in mice. This paper details the synthesis of the correct structure of azaspiracid-1 by (1) the deft use of ring-closing cascade reactions to assemble the ABCD and FHI ring systems and (2) the use of a Stille coupling as a mild late-stage fragment linkage method.
