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.
