trans-Fused 6-9-6 tricyclic ether 2 was synthesized and conformational alternation of the oxonene ring was reproduced as was observed for that in the ciguatoxin molecule (ring F). SmI2-promoted intramolecular Reformatsky reaction of O-linked bicyclic compound 4 features the construction of an oxonane ring in the present synthesis. (C) 1997 Elsevier Science Ltd.
