Chemical modifications of chitosan. Part 5 - Homogeneous N,O-acylation of chitosan in dimethyl sulfoxide with cyclic acid anhydrides
By using soluble chitosan (1R)-(-)-10-camphorsulfonate salt (chitosan-CSA), N,O-acylated chitosans were prepared in dimethyl sulfoxide (DMSO) with cyclic acid anhydride under homogeneous conditions.
