Intermolecular addition of radicals to the 1,3-dioxin-4-ones an unsaturated side chain were attacked by radicals at the terminal double bond. In the case of irradiation of 32b in 1,3-1a,b and 2a,b with (-)-menthone incorporated as chiral auxiliary in 2-position were investigated. Photochemically dio
