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
通过三氟甲磺酸酐与部分三甲基甲硅烷基化的七-和六-O-(三甲基甲硅烷基)-α反应,实现了6-叠氮基-6-脱氧和6,6'-二叠氮基-二脱氧-α,α-海藻糖衍生物的有效合成, α-海藻糖在吡啶和 4-(N,N-二甲氨基)吡啶存在下。用叠氮化物置换和脱甲硅烷基化得到标题化合物,其代表相应的 6-氨基-和 6,6'-二氨基-海藻糖的潜在前体。
