The synthesis of hyaluronic acid oligosaccharides on polyethylene glycol (PEG) using an acylsulfonamide linker has been explored. Hyaluronic acid is a challenging synthetic target that usually involves the condensation of highly disarmed glucuronic acid building blocks. Amine-ended PEG monomethyl ether was efficiently functionalized with a hydroxyl-terminated acylsulfonamide linker. Suitably protected D-glucosamine (GlcN) and D-glucuronic acid (GlcA) monosaccharide building blocks were coupled… Expand
