Flash vacuum pyrolysis of the 8-oxa-3,4-diazatricyclo-[,6]oct-4-enes (7) resulted in rearrangement to give the - 1-amino-2-formylpyrroles (7), presumably via the 1,4,5-oxadiazocines (14)whereas that of the 8-aza analogues (8) gave the 3a,6a-dihydropyrrolo[2,3-clpyrazoles (12) by a different type of rearrangement.
