  描述：

  3,4:5,7-di-O-isopropylidene-1,2-dideoxy-D-manno-hept-1-ynitol 在 palladium on activated charcoal copper diacetate 、 氢气 、 sodium ascorbate 作用下， 以 甲醇 、 水 、 叔丁醇 为溶剂， 反应 4.0h， 生成 4-(2,3-O-isopropylidene-mannopyranosyl)-1-(3-deoxy-β-D-glycero-D-gluco-septanosyl)-1,2,3-triazole

  名称：

  Synthesis of substituted septanosyl-1,2,3-triazoles

  摘要：

  A carbohydrate-based oxepine, derived from 2-deoxy-D-arabino-hexopyranose, was used to prepare a family of septanosyl-1,2,3-triazoles in four steps. DMDO mediated epoxidation of the oxepine followed by trapping of the intermediate 1,2-anhydroseptanose by sodium azide gave the beta-substituted glycosyl azide. The septanosyl azide was then reacted with a number of alkynes under thermal Huisgen or copper(I) mediated reaction conditions. Hydrogenolysis of benzyl protecting groups gave substituted septanosyl-1,2,3-triazoles. The new septanose-based structures were then evaluated as potential glycosidase inhibitors.
