  描述：

  (2R,3R,4R,5S)-4-Benzyloxy-2-benzyloxymethyl-1-nonyl-piperidine-3,5-diol 在 咪唑 、 四丁基氟化铵 、 sodium hydride 作用下， 以 四氢呋喃 、 N,N-二甲基甲酰胺 为溶剂， 反应 35.0h， 生成 (3S,4R,5R,6R)-4,5-Bis-benzyloxy-6-benzyloxymethyl-1-nonyl-piperidin-3-ol
  参考文献：
  名称：

  A stereodivergent approach to 1-deoxynojirimycin, 1-deoxygalactonojirimycin and 1-deoxymannojirimycin derivatives

  摘要：

  A stereodivergent synthesis of N-alkylated 1-deoxygalactoncjirimycin and 1-deoxymannojirimycin derivatives has been achieved from a protected 1-deoxynojirimycin intermediate having two free OH groups tactically positioned at C-2 and C-4. The inversion of configuration of the secondary alcohols was performed by way of a Swern oxidation followed by a highly diastereoselective reduction using NaBH4 or L-Selectride.
