Remote functionalization: Cyclic alkoxylation onto aromatic ring via radical pathway

Article abstract of DOI:10.1016/0040-4039(96)00313-9

Oxidative cyclization of alcohols containing an aromatic ring with (diacetoxyiodo)benzene and iodine gave the corresponding cyclic ethers via alkoxy radicals in good yields. The present method is very useful for the direct preparation of flavonoid and vitamin E analogues from the alcohols.
