A rhodium-catalyzed decarbonylative aerobic oxidation of cyclic α-diketones has been developed for the first time, where the regioselective formations of α-pyrones and isocoumarins have been achieved. The current decarbonylative aerobic oxidation pathway proceeds via the C-C bond cleavage followed by a C-O bond formation, representing a biomimetic oxidation approach to unsaturated six-membered cyclic lactones. The unique ability of rhodium catalysts to induce the decarbonylative aerobic oxidation opens up a new synthetic toolbox that utilizes the "regioselective single carbon" extrusion strategy.

Appropriately substituted benzoic acids (Ia-Ij) on treatment under reflux with 1-bromoacetophenone and potassium carbonate in the presence of very small quantity of water yield the corresponding benzoylmethyl benzoates (IIa-j), which undergo cyclization w
