1.
Four novel 1′-iodopropargyl glycosides(3a~3d) in yields of 75%~90% were synthesized from four monosaccharides(D-glucose,D-galactose,D-mannose and D-ribose) by glycosidation with propargyl alcohol in the presence of acid,and then iodo-substitution using base as a catalyst in yields of 75%~90%.
以四种单糖(D-葡萄糖、D-半乳糖、D-甘露糖和D-核糖)为原料,先在酸催化下与炔丙醇完成糖苷化反应(产率60%~80%);然后在碱催化下碘代合成了四个新型1′-碘代炔丙基糖苷类化合物(3a~3d,产率75%~90%),其结构经1H NMR表征。

6) iodoalkyne
炔基碘
1.
Seven 1-iodoalkynes in yields of 78%~91% were synthesized by reaction of terminal alkynes and cesium hydroxide in dry THF at room temperature for 3 h followed by treatment with iodine.
端炔与氢氧化铯在无水THF中于室温反应3h后与碘作用合成了7个炔基碘,收率78%~91%。
补充资料:炔丙基碘
分子式:HCC CH2I
CAS号:
性质:又称3-碘丙炔(3-iodopropyne)。室温下为液体。沸点115℃。不溶于水,溶于醇、醚等有机溶剂。分子中碘原子很活泼,易水解为丙炔醇;与乙醇钾反应生成丙炔基乙基醚;与硫化钠反应生成二炔丙基硫醚。用银氨或铜氨溶液处理可生炔银或炔铜沉淀;能催化氢化,也能与卤素及卤化氢回民。由炔丙基醇与碘化银在磷酸中反应制取。用于有机合成。
