3'-Sulfated and 3',6'-disulfated Lewis x trisaccharides have been prep
ared through selective sulfation of methyl zyl-alpha-L-fucopyranosyl)-
beta-D-glucopyranoside, followed by catalytic hydrogenolysis. In a sim
ilar manner, 3',6-disulfated and 3',6,6'-trisulfated Lewis x trisaccha
rides have been !;electively obtained from methyl zyl-alpha-L-fucopyra
nosyl)-beta-D-glucopyranoside. (C) 1998 Elsevier Science Ltd. All righ
