Treatment of the endo-thioester group substituted norbornenes 3a-3d with iodine in aqueous tetrahydrofuran at 25 °C gave the novel methylthio group rearranged lactonization products 4a-4d in 80% yields; iodolactonization reaction of 9 was applied to the synthesis of noveldiacetaltrioxa-cage compound 13.
