In a previous papeti in this series, we described the synthesis of L-fucosyldisaccharides having sulfate groups at C-3 or C-4. Such r\_-fucosyl-oligosaccharides occur naturally as a part of the structure of fucoidan, a sulfated L-fucose polysaccharide, know to possess anticoagulant acticity 3,4 This

✦ Synopsis
Synthesis of methyl 2-O-alpha-L-fucopyranosyl-alpha-L-fucopyranoside 3- and 4-sulfate was accomplished through the use of a key glycosyl donor, methyl 2,3,4-tri-O-benzyl-1-thio-beta-L-fucopyranoside, with methyl 2,3-O-isopropylidene-alpha-L-fucopyranoside and methyl 4-O-acetyl-3-O-benzyl-alpha-fucopyranoside as acceptors.
