The copper-catalyzed reaction of ethyl 4-azido-6-O-acetoxy-2,3,4-trideoxy-α-d-erythro-hex-2-enopyranoside with various functionalized alkynes gave the corresponding 1-(ethyl 6-O-acetyl-2,3,4-trideoxy-α-d-erythro-hex-2-enopyranos-4-yl)-1,2,3-triazole derivatives in quite good yields, which could be transformed into (ethyl 2,3,6-tri-O-acetyl-4-deoxy-α-d-mannopyranosyl)-1H-1,2,3-triazole by a simple bis-hydroxylation.
在铜催化下,4-叠氮-6-O-乙酰氧基-2,3,4-三脱氧-δ±-d-赤式-己-2-烯吡喃糖苷乙酯与各种官能化炔类化合物发生反应,得到了相应的 1-(6-O-乙酰基-2,3,4-三脱氧-δ±-d-赤式-己-2-烯吡喃糖苷-4-基)-1,2,3-三唑衍生物、这些衍生物可通过简单的双羟基化反应转化为(乙基 2,3,6-O-三乙酰基-4-脱氧δ±-d-吡喃甘露糖基)-1H-1,2,3-三唑。
