We describe a new general method for the synthesis ofmedium-sized lactones under mild conditions involving β-scissionof alkoxy radicals derived from catacondensed lactols as a key stepand its application to an efficient newsynthesis of a naturallyoccurring 10-membered lactone, phoracantholide I[(+−)-decan-9-olide].

We describe an efficient new synthesis of 15-membered cyclic ketones, exaltone and (±)-muscone, based on a three-carbon annelation of cyclic ketones followed by the regioselective radical cleavage of the fused bond of the resulting bicyclic systems.
