A stereocontrolled convergent synthesis of a DEFG-ring model compound of gambieric acids, highly potent antifungal marine polycyclic ether natural products, has been achieved based on Suzuki—Miyaura coupling. Conformational analysis of the model compound revealed that the nine-membered F-ring exists exclusively as a single stable conformer, as opposed to that of ciguatoxins.
