Abstract: The title compound, N,N-dibenzyl-1-(1-[(4-methyl-2-phenyl-4,5-dihydrooxazol-4-yl)methyl)]-1H-1,2,3-triazol-4-yl)methanamine was synthesized in high yield by 1,3-dipolar cycloaddition reaction of 4-(azidomethyl)-4-methyl-2-phenyl-4,5-dihydrooxazole and N,N-dibenzylprop-2-yn-1-amine in toluene at reflux. The structure of this product was established on the basis of NMR spectroscopy (1H, 13C), Elemental Analysis and MS data.

Abstract: Low molecular weight 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 functionalization of the amf unit by reductive amination with 4-(hexyloxy)aniline in presence of NaBH3CN was achieved in high yield. The chemical structure of the targeted 4-(hexyloxy)aniline-linked chitooligosaccharide-2,5-anhydro-D-mannofuranose was fully characterized by NMR spectroscopy, MALDI-TOF mass spectrometry and size-exclusion chromatography. This synthesis opens the way to a new generation of COSamf derivatives with potential amphiphilic properties.
