The 4,5-bridged pyrrol-2,3-diones 3, obtained from cyclocondensation reactions of the N,N-disubstituted hydrazones 2 and oxalyl dichloride, can be rearranged into the corresponding diaza propellanes 4 via a thermally initiated Fischer-indolization process.Their molecular structure is confirmed with aid of an X-ray structure determination of 4a and chemical degradation reactions leading to the tetracyclic indole systems 5.
