    A variety of sialyl-alpha-(2-->3)-neolactotetraose (IV3 NeuAcnLcOse(4) or IV(3)NeuGcnLcOse(4)) derivatives (23, 31-37, 58-60) modified at C-2 of the GlcNAc: residue have been synthesized. The phthalimido group at C-2 of GlcNAc in 2-(trimethylsilyl)ethyl (3,6-di-O-benzyl-2-deoxy-2-phthalimido-beta-D-glucopyranosyl)-(1-->3)-(2,4,6-tri-O-benzyl-beta-D-galactopyranosyl)-(1-->4)-2,3,6-tri-O-benzyl-beta-D-glucopyranoside (5) was systematically converted to a series of acylamino groups, to give the per-O-benzylated trisaccharide acceptors (6-11). On the other hand, modification of the hydroxyl group at C-2 of the terminal Glc residue in 2-(trimethylsilyl)ethyl (4,6-O-benzylidene-beta-D-glucopyranosyl)-(1-->3)-(2,4,6-tri-O-benzyl-beta-D-galactopyranosyl)-(1-->4)-2,3,6-tri-O-benzyl-beta-D-glucopyranoside (42) gave three different kinds of trisaccharide acceptors containing D-glucose (49), N-acetyl-D-mannosamine (50), and D-mannose (51) instead of the GlcNAc residue. Totally ten trisaccharide acceptors (5-11 and 49-51) were each coupled with sialyl-alpha-(2-->3)-galactose donor 12 to afford the corresponding pentasaccharides (14-21 and 52-54) in good yields, respectively, which were then transformed into the target compounds. Acceptor specificity of the synthetic sialyl-alpha-(2-->3)-neolactotetraose probes for the human alpha-(1-->3)-fucosyltransferases, Fuc-TVII and Fuc-TVI, was examined.
