Article Abstract

NOE-based analysis of the disaccharide β-Gal-(1 → 3)-β-Glc-OMe (1), especially a diagnostic Gal1-Glc4 NOE detected in a HSQC-NOESY spectrum, reveals the existence of the anti-ψ conformer in aqueous solution in addition to the major syn conformer. This result provides experimental proof of conformational flexibility around the aglyconic bond of β-(1 → 3) disaccharides, in contrast to previous studies that suggested that the flexibility around this linkage was restricted to the syn conformational region.
