2-Alkenyl-6-methyl-4H-1,3-dioxin-4-ones, adducts of diketene to alkenals or alkenones, are useful synthons which are applicable to photocycloadditions to construct multiply-functionalized alicyclic compounds via stereoselective intramolecular path.Some of the cage-shaped photoproducts showed extraordinary spectroscopic features.
