  • Enantiospecific synthesis of (−)-5-epi-shikimic acid and (−)-shikimic acid
    作者:Shende Jiang、Kevin J. McCullough、Boualem Mekki、Gurdial Singh、Richard H. Wightman
    DOI:10.1039/a700389g
    日期:——
    Diastereoselective reaction of 2,3-O-isopropylidene-D-ribose with allylmagnesium chloride gave a 5∶1 mixture of triols 4 and 5, which were then converted to nitrones 8 and 9. Intramolecular nitrone cycloaddition gave the isoxazolidines 10 and 11, which on acetylation gave the corresponding acetates 12 and 13 which were separated by repeated crystallisation. The major adduct 12 was converted to (-)-5-epi-shikimic acid 2. Reaction of the ribonolactone derivative 20 with allylmagnesium chloride gave the hemiacetal 21. Reduction of compound 21 with DIBAL afforded exclusively the diol 22, which was desilylated to give the triol 5. Similar chemistry to that employed for the synthesis of (-)-5-epi-shikimic acid 2 with the diol 5 resulted in the synthesis of (-)-shikimic acid 1.
    2,3-O-异亚丙基-D-核糖与烯丙基氯化镁发生非对映选择性反应,生成 5∶1 的三醇混合物 4 和 5,然后转化为硝酮 8 和 9。分子内的硝酮环化反应生成异噁唑烷 10 和 11,乙酰化反应生成相应的乙酸盐 12 和 13,通过反复结晶分离。主要加合物 12 转化为 (-)-5- 表莽草酸 2。核糖酸内酯衍生物 20 与烯丙基氯化镁反应生成半缩醛 21。 化合物 21 与二乙酰胆碱还原生成二元醇 22,二元醇 22 经过脱反应生成三元醇 5。用二元醇 5 合成(-)-5-表莽草酸 2 的化学反应与合成(-)-莽草酸 1 的化学反应类似。
  • Synthesis of α,β-unsaturated aldehydes from the fragmentation of isoxazolidines with methyl iodide
    作者:Michel P. van Boggelen、Bart F.G.A. van Dommelen、Shende Jiang、Gurdial Singh
    DOI:10.1016/0040-4039(95)00107-n
    日期:1995.3
    Isoxazolidines when treated with methyl iodide in THF, under reflux readily afford α,β-unsaturated aldehydes and quaternary ammonium iodide alcohols.
    当异丁唑烷在THF中用甲基处理时,在回流下容易得到α,β-不饱和醛和化季醇。
  • Methyl iodide mediated cleavage of the nitrogen-oxygen bond of isoxazolidines
    作者:Michel P. van Boggelen、Bart F.G.A. van Dommelen、Shende Jiang、Gurdial Singh
    DOI:10.1016/s0040-4020(97)10125-9
    日期:1997.12
    A novel method of N-O bond cleavage in isoxazolidines is described. Treatment of isoxazolidine with excess of methyl iodide in THF under reflux gave the quaternary ammonium iodide alcohol and the alpha,beta-unsaturated aldehyde. The former can be converted to the latter via the Swern oxidation. (C) 1997 Elsevier Science Ltd.
