Abstract Methyl (methyl 3-acetamido-2, 3-dideoxy-α-D-ribo-hexopyranosid) uronate was prepared from methyl 3-acetamido-4O-benzoyl-6-bromo-2, 3, 6-trideoxy-α-D-ribo- hexopyranoside (2) by a sequence or reactions involving photodecom̄position of the 6- azido-4-hydroxyl analog of 2, followed by successive mild hydrolysis of the intermediate imine 8 (to afford the aldehyde 11), oxidation, and esterification. In contrast, mild ...
