Amylose oxidized with nitrogen dioxide, having D.O. by (C=O) 0.38 and by (COOH) 0.94 was converted into its oxime, which after reduction with sodium and isopropyl alcohol yielded (1→4)‐2‐amino‐2‐deoxy‐α‐glucopyranuronan with D.S. by (NH 2 ) 0.30 and by (COONa) 0.85. After acetylation and O‐deacetylation (1→4)‐2‐acetamido‐2‐deoxy‐α‐d‐glucopyranuronan with D.S. by (NHCOCH 3 ) 0.28 and by (COONa) 0.80 was obtained.
