✦ Synopsis

The 1H NMR spectra of a series of acridine-derived Tro gerÏs base analogs substituted at various positions were registered. Also the 1H NMR characteristics of the Ðrst heterocyclic asymmetric Tro gerÏs base analog constituted of one acridine and one phenanthroline nucleus with the two corresponding symmetric Tro gerÏs bases were compared. The analysis of the NMR data clearly shows that the chemical shifts of endo/exo protons of heterocyclic Tro gerÏs base analogs are strongly dependant on the nature and geometry of the constituting heterocycles.

The ' H and '% NMR spectra of 15 modified representatives of Troger's base were recorded and the corresponding signals assigned. In 'H NMR, the appearance of the AABB'CC'(XX) system, after irradiation of H,(H,), is deceptively simple and should not be first-order analysed. The 13C chemical shifts an

The 'H and I3C NMR spectra of an asymmetric Troger's base were recorded and the corresponding signals assigned on the basis of long-range coupling constants and 'H-13C correlations. In 1H NMR, ambiguities in the assignment of e m and endo hydrogen atoms and in the long-range couplings between the me
