A convergent synthetic route to the BCDEring system of yessotoxin, a polycyclic ether marine toxin related to diarrhetic shellfish poisoning, has been developed. The key feature of the present synthesis is the alkylation of acetylene with the B and E ring units, which were prepared from a common intermediate. The alkyne functionality was directly converted to a 1,2-diketone by ruthenium oxidation
