SYNTHESIS AND AROMATIZATION OF INDOLE DERIVATIVES OF N-IMIDOYLDIHYDROAROMATIC COMPOUNDS

Article abstract of DOI:10.1007/BF00506106

The reaction of indole (methylindoles) with a number of pyridine bases, imidazole, and benzimidazole in the presence of benzimidazolyl chlorides gave N-imidoyl derivatives of dihydro-α(γ)-3-indolylheterocyclic compounds, the aromatization of which under the influence of triphenylmethyl perchlorate or 1-oxo-2,2,6,6-tetramethylpiperidinium perchlorate leads to perchlorates of N-imidoyl heteroaromatic cations.
