Article

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.

Keywords
