Abstrakt: An efficient synthesis of 6-azido-6-deoxy and 6,6'-diazido- dideoxy-α,α-trehalose derivatives was achieved by reaction of trifluoromethanesulfonic anhydride with partially trimethylsilylated heptakis- and hexakis-O-(trimethylsilyl)-α,α-trehalose in the presence of pyridine and 4-(N,N-dimethylamino)pyridine. Displacement with azide and desilylation afforded the title compounds, which represent potential precursors for the corresponding 6-amino- and 6,6'-diamino-trehaloses. [ABSTRACT FROM AUTHOR]
