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

✦ Synopsis
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 metbylene hydrogens were resolved.

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
The complete assignments of 1H and 13C NMR data for a series of synthesized diosgenyl saponin analogs are described, viz. diosgenyl b-D-glucopyranoside (1), diosgenyl a-L-rhamnopyranosyl- 7). The assignments were achieved using homo-and heteronuclear two-dimensional NMR techniques.
In addition to 1D NMR methods and 2D shift-correlated NMR techniques (COSY and HETCOR), spin-spin simulation and MMX calculations, to obtain the minimum energy conformation structure, were used for the complete 1 H and 13 C NMR assignments of stephalic acid.
