The direct esterification reaction of dextran with c~-naphthylacetic acid (a model bioactive carboxylic acid) is studied in homogeneous phase using pyridine-sulfonyl chloride as catalyst. The structure of the resulting adducts was determined by means of infra-red, 1H nuclear magnetic resonance (n.m.
This work deals with the coupling of model bioactive carboxylic acids (l-naphthylacetic acid, 2-(6-methoxy-2-naphthyl)propionic acid (naproxen) and nicotinic acid) to dextran by direct reaction with their potassium salts using pyridine/sulfonyl chloride as activating agent. The structure of the resu
