Description Benzyl q-o- [ 2, q, 6-tri-O-benzyl-3-O- ( q-methoxybenzyl } -/3- D-galactopyranosyl]-2-~3,6-tri-O-b~zyl-/J-D-g~copyranoside (q) was
synthesised from benzyl lact~'~ide (2) via regioselective protection of 3'-OH with q-methoxybenzyl group. Oxidative deprotection of q afforded the valuable acceptor 5. The trisaccharide 7 was obtained through coupling of 5 and phenyl 2-deoxy-3,q,6-tri-O-acetyl-2-pht-halimido-l-thio-#-D-glucopyranoside (6]. The desired tetrasaccha-
ride I was built up through fucosylation of the benzylidene deri- vative 11 o b t a i n e d from 7.
