Ciguatoxin CTX3C is a representative congener of the ciguatoxins, which are known to be the principal causative-agents of ciguatera seafood poisoning. The structure of CTX3C spans over three nanometers and is characterized by thirteen ether rings. To attain a practical construction of this molecule, efficient supplies of the structural fragments are crucial. Herein we report the convergent synthesis of the ABCDE ring fragment featuring (i) alkylative coupling of the AB ring and E ring, and (ii) ring-closing olefin metathesis.
