Abstract:  Preparation and properties of N-alkyl derivatives of aspartic acid are described and the 1H-n.m.r. spectra of these compounds are discussed. The protonization constant of the amine nitrogen and the conformation of the αCH—ßCH2 fragment in neutral and alkaline solution in D2O were determined from the 1H-n.m.r. spectral data. These results were considered when studying the influence of formation of supermolecular associates upon conformation of the fragment under investigation.
