The synthesis of the FG subunit of the pectenotoxins is reported herein. The synthesis hinges on the preparation of an appropriately functionalized acyclic precursor using a Z-selective Wittig reaction. Further elaboration using two sequential cyclization reactions furnished the tetrahydrofuran F ring and the tetrahydropyran G ring, respectively.
