The methyl glycoside of a tetrasaccharide isolated from heparin, methyl O-(α-L-idopyranosyluronic acid)-(1 → 4)-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-(1 → 4)-O-(β-D-glucopyranosyluronic acid)-(1 → 3)-O-β-D-galactopyranoside disodium salt and a trisaccharide derivative thereof, methyl O-(α-L-idopyranosyluronic acid)-(1 → 4)-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-(1 → 4)-O-β-D-glucopyranosyluronic acid disodium salt, were synthesized using a block-type strategy. A suitable protected disaccharide block of iduronic acid and glucosamine (IdoA-GlcN) was used as a key intermediate for the syntheses and was glycosidated with a protected galactose derivative and a disaccharide block of glucuronic acid and galactose (GlcA-Gal) to give tri- and tetra-saccharide derivatives, respectively. Deprotection gave the target compounds.
