摘要：

Free radical addition of para-toluenesulfonyl iodide to alkenols occurs readily to give functionalised beta-iodosulfones as single regioisomers. Cyclisation to give cyclic ethers is effected by treatment with potassium carbonate in methanol. An anomalous reaction, where a substituted alkenol cyclises directly to give an iodotetrahydropyran, is also discussed.
