Abstract
The debenzylation of N-benzyl-substituted 1H-pyrrolo[1,2-a]imidazoles and 4H-pyrrolo-[1,2-a]benzimidazoles under the influence of sodium in liquid ammonia was studied. From the IR and PMR spectra it was established that the compounds obtained have the structures of 7H-pyrrolo[1,2-a0]imidazole and 3H-pyrrolo[1,2-a]benzimidazole derivatives. The debenzylation of 2,3-diphenyl-4-benzylpyrrolo[1,2-a]benzimidazole proceeds with the simultaneous reduction of the pyrrole ring and the formation of 1H-2,3-dihydro-2,3-diphenylpyrrolo[1,2-a]benzimidazole.
