  • Method of synthesising 6-deoxy-6-amino-?-D-glucopyranoside-containing polymers and their precursors
    Patent number: 11021547
    Abstract: The invention provides an improved method of synthesising derivatives of ?-D-glucopyranoside-containing polymers, such as chitin, chitosan, cellulose, amylose, pullulan, curdlan, inulin, guar gum or cyclodextrin. The method includes reacting a polymer of formula (III) with a cyclic imide to form a polymer of formula (I) thereby introducing a nitrogen functionality at the 6-position and providing access to 6-deoxy-6-amino-?-D-glucopyranoside-containing polymers.
    Type: Grant
