| abstract | The invention relates to a method of preparation of 6-azido-2,4-diacetamido-2,4,6-trideoxy-D-mannose. This method comprises the chemical reaction of compound of formula (X). Wherein: R 1 can be a C 1 to C 6 alkyl including methyl, ethyl, isopropyl; aryl including phenyl; each of these groups being substituted or not; and R 2 can be a C 1 to C 6 alkyl including methyl, ethyl, isopropyl, te/t-butyl, isobutyl; each of these groups being substituted or not; with a deprotecting reagent comprising a Lewis or Bronsted acid in a polar aprotic solvent, thereby obtaining a free C-1 OH group. The method can also start with the preparation from commercially available D-galactose pentaacetate, D-galactose tetraacetate or tetraacetyl D-galactosyl trichloroacetimidate. According to the invention the step of deprotecting the anomeric position avoids the use of cerium and allows the easy purification of 6-azido-2,4-diacetamido-2,4,6-trideoxy-D-mannose. |
