Molecules of pyrroloquinolines obtained from substituted 4-, 5-, 6-, and 7-aminoindoles and β-keto esters (acetoacetic, trifluoroacetoxy, and oxaloacetic esters) in quinoline and hydroxyquinoline forms have been investigated by semi-empirical calculations. On the basis of the experimental data and the calculated 1H NMR spectra spectral criteria have been found for the assignment to one or the other tautomeric form.
