Synthesis of a versatile tetrasaccharide of sialyl Le(x) and Le(x) antigens

Benzyl 4-O-[2,4,6-tri-O-benzyl-3-O-(4-methoxybenzyl)-β-D-galactopyranosyl]2, 3,6-tri-O-benzyl-β-D-glucopyranoside (4) was synthesized from benzyl lactoside (2) via regioselective protection of 3'-OH with 4-methoxybenzyl group. Oxidative deprotection of 4 afforded the valuable acceptor. 5. The trisaccharide 7 was obtained through coupling of 5 and phenyl 2-deoxy-3,4,6-tri-O-acetyl-2-phthalimido-1-thio-β-D-glucopyranoside (6). The desired tetrasaccharide 1 was built up through fucosylation of the benzylidene derivative 11 obtained from 7.

Treatment of benzyl O-β-D-galactopyranosyl-(1->3)-2-acetamido-2-deoxy-4,6-O-isopropylidene-β-D-glucopyranoside with tert-butylchlorodiphenylsilane afforded the 6'-O-tert-butyldiphenylsilyl ether, which was converted into the 3',4'-O-isopropylidene derivat

Glycosyl Imidates, 42.- Selectively Protected Lactose and 2-Azido Lactose, Building Blocks for Glycolipid Synthesis

Performing regioselective alkylation at 3'-OH of benzyl β-lactoside 1 by the stannylation method we prepared the 3'-OH- and 4'-OH-unprotected lactose derivatives 5 and 10 and the 4'-OH-unprotected lactose derivative 9 containing a different protecting gro
