Oxidation of p-methoxyphenol, 4-methoxynaphthol and 4-acetamidophenol with iodobenzenediacetate in various alcohols as solvent afforded the corresponding mixed quinone or naphthoquinone monoketals in good yield. Oxidation of p-methoxyphenol in the presenc

(Chemical Equation Presented) p-Iodophenol and its O-MOM-protected ether can be converted into iodoamines 2. These give cross-conjugated ketones 3 on oxidation with hypervalent iodides in the presence of methanol, and the ketones undergo radical cyclization. Exposure of the products to acid or sequential treatment with a Grignard reagent and acid effects rearomatization to produce benzo-fused nitrogen heterocycles 4.
