Abstract
PURPOSE: To obtain a sugar polymer containing free amino groups, by treating a polymer having, as a unit, 1,6-anhydro-3-azido-2,4-di-O-benzyl-3-deoxy-β-D-glucopyranose with lithium aluminum hydride.
CONSTITUTION: The titled amino sugar polymer of formula II is obtained by reacting an azido sugar polymer of formulaI, (where Bn is benzyl, n is 70W 120) is reacted with lithium aluminum hydride at about 60W70°C in a solvent such as tetrahydrofuran. The above azido sugar polymer is obtained by polymerizing 1,6-anhydro-3-azido-2,4-di-O-benzyl-3-deoxy-β-D-glucopyranose in the presence of phosphorus pentafluoride in a solvent such as methylene chloride.
USE: Medicines.
