| 摘 要： | 在酸和氯化锌催化下D-核糖的亚异丙基化反应中得到的反应混合物,经柱色谱及重结晶分离,除获得产物1,4-脱水-2,3-氧-亚异丙基吡喃核糖外,首次分离出1,5-2,3-双-氧-亚异丙基核糖。测定并比较了这两种产物的~1H和~(13)C核磁共振谱。聚合试验结果表明这类双亚异丙基化核糖与单亚异丙基化脱水核糖不同,它不具有正离子开环聚合活性。

| Abstract: | Isopropylidene derivatives of D-ribose are prepared by condensation of D-ribose and acetone in the presence of acid and zinc chloride, after seperation by a column chromatography and recrystallization. 1, 5-2,3-di-O-isopropylidene-D-ribofuranose and 1,4-anhydro-2,3-O-isopropylidene-D-ribopyranose are obtained. It is the first time that 1,5-2,3-di-O-isopropylidene-D-ribofuranose has been separated from 1, 4-anhydro-2,3-O-isopropylidene-D-ribopyranose by ~1H and ~(13)C NMR spectra. The cationic ring-opening polymerization of the ribose derivatives is studied, but polysaccharides of 1,5-2, 3-di-O-isopropylidene-D-ribose is not obtained. |
