Synthetic studies of yessotoxin, a polycyclic ether implicated in diarrhetic shellfish poisoning: Convergent synthesis of the BCDE ring system via an alkyne intermediate

A convergent synthetic route to the BCDE ring 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 rin
