Stereoselective synthesis of the fully functionalized HIJ-ring framework of ciguatoxin

An efficient convergent synthetic route to construct the HIJ-ring system of ciguatoxin was achieved via stereo controlled eight-membered ring formation by using acetylene cobalt complex and subsequent six-membered ring formation through intramolecular 1,4-addition reaction.
