which reveal strong conformational preferences. The rearrangement of the 2H-pyrroles was studied under both thermal and acid-catalysed conditions. The results show that 2,2-disubstituted 2H-pyrroles only rearrange easily by [1,5]-sigmatropic shifts if they do not have further substituents on C-3 and C-4. 2-Pyrrolylmethyl-2H-pyrroles prefer to rearrange by a fragmentation-recombination mechanism.
