The alkoxy radicals formed by the reaction of steroidal cyclic hydroxyketones (1) and (2) with (diacetoxyiodo)benzene and iodine or mercuric oxide and iodine under oxygen atmosphere and irradiation with visible light undergo a new quintuple sequence beta-fragmentation-peroxidation-radical reduction-radical reduction-radical cyclization-beta-fragmentation reaction before being trapped by an atom of iodine.
