Abstract
Two fucotriosides with vicinal disubstitution alpha -L-Fuc-(1-->2)[alpha -L -Fuc-(1-->3)[alpha -L-Fuc-OPr (1) and alpha -L-Fuc-(1-->3)[alpha -L-Fuc-(1- ->4)]alpha -L-Fuc-OPr (2), which are related to fragments of natural polysa ccharides fucoidans, have been synthesized together with constituent disacc harides 3-5, Spectral and conformational properties of tri- and disaccharid es have been investigated by H-1, C-13 and NOE NMR spectroscopy.
