| Abstract: | UV.-irradiation (λ = 254 nm) of the hydroxy-enones 3 and 6 in acetonitrile results in the cyclization to the unstable isomeric allylic alcohols 4 and 7 , which dehydrate easily to the isolated unsaturated ether 5 and 8 . The racemic γ,δ-dihydroxy-enone 9 upon irradiation under the same conditions gives rise to the exclusive formation of the furane-compound 11 . |
