The oxidation of 9-xanthenones with lead(IV) acetate afforded 3a,3b,6a,12b-tetrahydro-2H-difuro[3,2-a:3′,2′-c]xanthene-2,5,7(3H,6H)-triones in addition to other products. Characterization of the di-γ-lactones and the difference between the oxidation reaction of lead(IV) and manganese(III) acetates in the 9-xanthenone system are discussed.
