Abstract

Chitooligosaccharide with one 2,5-anhydro-D-mannofuranose unit at the reducing end (COSamf) was prepared by nitrous deamination of fully N-deacetylated chitosan. The oxidation of the amf-unit by chlorite sodium was achieved in high yield. The chemical structure of the targeted chitooligosaccharide-2,5-anhydro-D-mannonic acid with a degree of polymerization ~10 was fully characterized by NMR spectroscopy, MALDI-TOF mass spectrometry and size-exclusion chromatography. The success of this synthesis opens the way to a new generation of end-functionalized COS building blocks.
