Oligosaccharide derivatives from sanqi, a Chinese herbal medicine derived from Panax notoginseng, methyl β-D-galactopyranosyl-(1→3)-[α-L-arabinofuranosyl- (1→6)]-α-D-galactopyranoside, diosgenyl β-D-galactopyranosyl-(1→3)-[α-L-arabinofuranosyl- (1→6)]-α-D-galactopyranoside, and methyl β-D-galactopyranosyl-(1→3)-[α-L-arabinofuranosyl- (1→6)]-α-D-galactopyranosyl-(1→4)-β-D- galactopyranosyl-(1→3)-[α-L-arabinofuranosyl-(1→6)] -α-D-galactopyranoside, were synthesized under standard glycosylation conditions. An unexpected α-(1→4) linkage was formed predominantly in the presence of neighboring participation group during regioselective synthesis of hexasaccharide via 3+3 strategy.
