N.M.R. SPECTRAL STUDY OF α- AND β-L-ARABINOFURANOSIDES

Anomeric pairs of L-arabinofuranosides of various aliphatic alcohols were synthesized and then investigated by n.m.r. spectroscopy.The 13C-n.m.r. glycosylatation shift of these L-arabinofuranosides is very similar to that of L-arabinopyranosides and other glycopyranosides reported previously.The 3JH-1,H-2 value of these α-L-arabinofuranosides is significantly different from that of the β anomers and can be used for the determination of the anomeric configuration.However, in contrast to the case of glycopyranosides, the 1JC-1,H-1 values of each anomeric series of L-arabinofuranosides are very similar to each other.Some disaccharides containing an L-arabinofuranoside unit were also investigated by n.m.r. spectroscopy.
