The synthesis of some acyclic C-nucleoside analogs possessing thiadiazole rings was achieved by the heterocyclization of the 4-arylthiosemicarbazones of D-galactose, D-glucose, D-mannose, D-arabinose, and lactose, Acetylation of the thiadiazoles afforded the corresponding 2-(N-acetylarylamino)-5-polyacetoxyalkyl-1,3,4-thiadiazoles and periodate oxidation gave the corresponding 5-(arylamino)-1,3,4-
通过 D-半乳糖、D-葡萄糖、D-甘露糖、D-阿拉伯糖和乳糖的 4-芳基缩氨基硫脲杂环化,合成了一些具有噻二唑环的无环 C-核苷类似物,噻二唑的乙酰化得到相应的 2 -(N-乙酰基芳基氨基)-5-聚乙酰氧基烷基-1,3,4-噻二唑和高碘酸盐氧化得到相应的5-(芳基氨基)-1,3,4-噻二唑-2-甲醛。
