Anionic Fries Rearrangements of Esters of ortho-Iodobenzyl Alcohols: Rapid Routes to Oestrone Methyl Ether and Its 9β Epimer, and Aryl Naphthalide Lignans

A fast, general, low-temperature rearrangement of ortho-iodobenzyl esters, triggered by lithium-iodine exchange, leads to isobenzofurans which are intercepted in situ by inter and intramolecular Diels-Alder (IMDA) reactions to produce a variety of carbocycles including natural lignans and steroids.
