Synthesis of novel quaternary chitosan derivatives via N-Chloroacyl-6-O-triphenylmethylchitosans.
Various quaternary chitosan derivative structures were synthesized by reacting N-chloroacyl-6-O-triphenylmethylchitosans with tertiary amines. Full substitutions were obtained from the quaternization reactions and the obtained water-soluble quaternary chitosan derivatives were thoroughly characterized with (1)H NMR, (13)C NMR, (1)H-(13)C HSQC NMR, and FT-IR.
