Photosensitized oxygenations in alcoholic solution of the furfural compounds 1,6-9 and the furanic compounds 10-17 yield the hydroxybutenolides 2a, 1, 20, 21, 22, the alkoxybutenolides 5, 19, 23, 24 and the unsaturated compounds 25 and 26.With rose bengal fixed on the polysaccharide resin Sephadex A 25 as sensitizer, the quantum yields of singlet oxygen formation in methanol or ethanol are higher (19 to 116percent) than those obtained with the commercial resin Sensitox.Kinetic results for these photo-oxygenations show the electronic influence of the substitution on C2 or C5.Depending on these substituants, several reaction pathways can be envisaged in order to explain the formation of the products.
