Abstract: Starting from D-galactose, per-O-acetylated (S)-TBMBcarboxylic acid derivant of methyl-4-amino-4-deoxy-D-glucopyranoside was prepared. The mechanism of the possible side reactions of the catalytic reduction from different types of azide sugar to the corresponding amino sugar was discussed. 1-O-Me-protection was selected for preventing the intramolecular dehydration of the 4-amino sugar, which was a key intermediate product in this synthetic process. The product was characterized by HRMS and 1H NMR spectroscopy and will be used as a molecular model to develop a new identification method of the D, L-configurations of amino sugar.

Key words: Azido sugar, Catalytic reduction, Methyl-4-amino-4-deoxy-D-glucopyranoside
