Pyran-4-ones bearing carboxylic acid side chains were prepared either by direct carboxylation with carbon dioxide or through oxidative cleavage of side chain olefins. Irradiation in a non-nucleophilic solvent yielded fused bicyclic lactones. The efficiency of the reaction was not dependent on ring substitution.
