An enantioselective synthesis of the halogenated medium-ring ether natural product (+)-obtusenyne is reported which uses the ring expansion of a seven-membered ketene acetal by means of a Claisen rearrangement to construct the core nine-membered oxygen heterocycle. The trans substituents across the ether linkage were established by using a transition-metal-catalyzed intramolecular hydrosilation reaction

The synthesis of five fused-bicyclic medium-ring lactones carrying identical ring-fusion to that in the polyether toxins is described using an enolate hydroxylation, intramolecular hydrosilation, Claisen rearrangement sequence.
