Chemical synthesis of a dextran model, poly‐α‐(1 → 6)‐anhydro‐D‐glucopyranose

Abstract
Poly‐α‐(1 → 6)‐anhydro‐D‐glucopyranose has been synthesized by the phosphorus pentafluoride‐catalyzed polymerization of l,6‐anhydro‐2,3,4‐tri‐O‐benzyl‐β‐D‐glucopyranose and subsequent debenzylation. Physical characterization establishes its high polymeric character and stereoregularity.
