Manganese(III)-based oxidation of a mixture of 3-(2-oxoethyl)piperidine-2,4-diones 5 and 1,1-diarylethenes 6 in acetic acid at reflux temperature gave structurally unique heterocyclic [4.3.3]propellanes 7 in high yields. Whereas a similar reaction using a catalytic amount of manganese(III) acetate at room temperature in air selectively yielded propellane-type endoperoxides 8 in moderate to good yields. The reaction using cyclic triketones 11 also afforded similar results. However, the manganese(III)-based dual cyclization of 2-(3-oxopropyl)-substituted cyclic diketones 15 was suppressed and most of the reaction stopped at the monocyclization stage. The mechanism for the formation of the propellanes and their derivatives was discussed.
