Exceptional neurotoxicity is associated with ciguatoxin. The ciguatoxin mimic 1, which contains the F-M framework of the natural product, has been prepared through a convergent synthesis. The two key steps were a Lewis acid mediated intramolecular reaction of a γ-alkoxyallylsilane with an acetal group and an SmI2 -mediated intramolecular Reformatsky reaction that permitted construction of the annelated hexahydrooxonin ring system.
