Abstract
Ten diether-type monoglycosyl and glycobiosyl glycerolipids, including 3-O-(4-O-β-D-galactopyranosyl-β-D-glucopyranosyl)-1, 2, -di-O-n-tetradecyl-sn-glycerol, a synthetic analogue of lactosyl ceramide, were synthesized and their stereochemistry was assigned unambiguously by 13C NMR using the values of C-H one bond couplings. Their 13C NMR were further analysed to show the diagnostic α-effect of glycosylation in these compounds depending on the anomeric configuration of the glycosyl residue linked to C-3'-O atom.
