Synthesis of a library of fucopyranosyl-galactopyranosides consisting of a complete set of anomeric configurations and linkage positions

A library composed of a complete set of fucopyranosyl-galactopyranosides was synthesized. A perbenzylated phenylthio fucopyranoside and a series of tri-O-benzyl-galactopyranosyl fluorides having single hydroxyl groups at the 2-, 3-, 4-, and 6-positions we

2-Deoxy-disaccharide approach to natural and unnatural glycosphingolipids synthesis

2-Deoxy-disaccharides were easily converted into glycosylphytosphingosines, as new and efficient precursors of natural and unnatural glycosphingolipids. Copyright (C) 2000 Elsevier Science Ltd.

SYNTHESIS OF SUBSTITUTED 2,7-DIOXABICYCLOHEPTANES: 1,2-ANHYDRO-3,4,6-TRI-O-BENZYL-AND 1,2-ANHYDRO-3,4,6-TRI-O-(p-BROMOBENZYL)-α-D-GALACTOPYRANOSE

The title compounds were synthesized from D-galactose via 9 steps.For obtaining stable, 1,2-blocked D-galactopyranose ethers, the 1,2-hydroxyl groups were protected with an ethylidene group instead of a 1-ethoxyethylidene group.The key intermediates for t

CHEMICAL SYNTHESIS OF A (12)-D-GLUCOPYRANAN

1,2-Anhydro-3,4,6-tri-O-benzyl-α-D-glucopyranose was polymerized with a number of Lewis acids.Phosphorus pentafluoride at -60 deg C caused polymerization to a product rich in β linkages.Other Lewis acids at higher temperatures gave perbenzylated polysaccharides of lower molecular weight with less stereoselectivity.Debenzylation of the most-regular derivative gave a polysaccharide whose specific rotation was +14.7 degree and whose (13)C-n.m.r. spectrum had six absorptions corresponding to those of natural (12)-β-D-glucopyranans and additional minor peaks presumably due to some α-anomeric configurations.It was estimated to have ca. 90percent of β linkages.
