Abstract
The complete assignments of H-1 and C-13 NMR data for a series of synthesiz ed diosgenyl saponin analogs are described, viz. diosgenyl beta-D-glucopyra noside (1), diosgenyl alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranos ide (2), diosgenyl alpha-L-rhamnopyranosyl-(1 --> 3)-beta-D-glucopyranoside (3), diosgenyl alpha-L-rhamnopyranosyl(1 --> 2)-alpha-L-rhamnopyranosyl-( 1 --> 3)-beta-D-glucopyranoside (4), alpha-L-rhamnopyranosyl-( 1 --> 2)-bet a-D-xylopyranosyl-(1 --> 3)-beta-D-glucopyranoside (5), a-L-rhamnopyranosyl -( 1 --> 2)-beta-L-arabinofuranosyl-( 1 --> 3)-beta-D-glucopyranoside (6) a nd alpha-L-rhamnopyranosyl-( 1 --> 2)-beta-D-glucopyranosyl-(1 --> 3)-beta- D-glucopyranoside (7). The assignments were achieved using homo- and hetero nuclear two-dimensional NMR techniques. Copyright (C) 1999 John Wiley & Son s, Ltd.
