英文摘要	The known 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl-(1 -> 3)-[2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl-(1 -> 6)1-2,4-di-O-acetyl-beta-D, glucopyranosyl-(1 -> 3)-2,4,6-tri-O-acetyl-alpha-D-glucopyranosyl-trichloroacetimidate (2) was chosen as glycosyl donor to couple with allyl 4,6-O-benzylidene-2-O-benzoyl-alpha-D-glucopyran-oside (4) to afford beta-(1 -> 3) linked pentasaccharide 5 in a stereo-specific manner. After removal of 4,6-O-benzylidene of 5, followed by coupling with 2,3,4,6-tetra-O-benzoyl-alpha-D-glucopyranosyl trichloroacetimidate (7), the blocked gluco-hexasaccharide (8) was regio- and stereo-specifically obtained. Deprotection of 8 provided the target sugar 9. Thus, a new method for the preparation of this kind of compounds was developed.
