Their structure elucidation and complete 111 and 13 C assignments have been performed by a combination of various one- and two-dimensional NMR experiments. Copyright (c) 2006 John Wiley & Sons, Ltd.

This work has been performed within the project ‘Biologically Active Natural Products, Synthetic Diversity’ (Department of Chemistry, Hannover University). AB - Three glycosides were isolated from Bougainvillea glabra and their structures were determined by extensive use of 1D and 2D NMR spectroscopy (H-1 and C-13). Compound 1 was identical to momordin IIc (quinoside D) [beta-D-glucopyranosyl 3-O-[beta-D-xylopyranosyl-(1 -> 3)-O-(beta-D-glucopyranosyluronic acid)] oleanolate], compound 2 was quercetin 3-O-alpha-L-(rhamnopyranosyl)(1 -> 6)-[alpha-L-rhamnopy-ranosyl(1 -> 2)]-beta-D-galactopyranoside and compound 3 was its derivative quercetin 3-O-alpha-L-(4-caffeoylrhamnopyranosyl)(1 -> 6)-[alpha-L-rhamnopyranosyl (1 -> 2)]-beta-D-galactopyranoside, a new natural product.

The internal competition of the two bindings sites in 2, the Ph-2 P=O group, and the iodine atom was identified by variable-temperature P-31 NMR. Energy optimization (PM3) and ROESY spectroscopy of 2 in the absence and presence of Rh* reveal that 2 prefers a conformation in the adducts, which is the least stable one in the free molecule, i.e., adduct formation is accompanied by a rotation of the Ph-2 P=O group about the C-2'-P bond.
