An operationally simple protocol for the synthesis of medium-sized lactones and macrolactones via an intramolecular ring expansion of cyclic ketones has been developed. Using this method, a series of 10- and 12-membered lactones was synthesized under mild conditions. Preliminary mechanistic studies showed that a radical pathway might be involved in this reaction.
