Various 1,2,3-triazole and 1,2,3,4-tetrazole fused multi-cyclic compounds were synthesized from carbohydrate derived azido-alkyne and azido-cyanide substrates. The acid sensitive 1,2-O-isopropylidene group of the furanosyl sugar was utilized for diversification to glycosides and nucleosides under Fischer glycosidation and Vorbruggen's conditions, respectively.
各种1,2,3-三唑和1,2,3,4-四唑融合的多环化合物是从来源于碳水化合物的叠氮-炔烃和叠氮-氰化物底物合成的。呋喃糖的酸敏感1,2-O-异丙烯基醚基团被用于在Fischer糖苷化和Vorbruggen条件下,分别多样化为糖苷和核苷。
