describe a newgeneral method for the synthesis of medium-sized lactones based on ring-enlargement via a regioselective β-scission of alkoxyl radicals generated by photolysis from the hypoiodites of several catacondensed lactols. The syntheses of 9-membered lactones from 65 fused lactols, 10-membered lactones including a naturally occurring lactone, phoracantholide I, from 66 or 75 fused lactols, and

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].
