  描述：

  2-benzyloxymethyl-4-(2-methylphenyl)-1-(4-methylphenylsulfonyl)pyrrolidin-3-one 在 palladium on activated charcoal 氢气 、 二异丁基氢化铝 作用下， 以 四氢呋喃 、 甲醇 、 正己烷 为溶剂， 反应 13.0h， 生成 (2R,3S,4S)-2-hydroxymethyl-4-(2-methylphenyl)-1-(4-methylphenylsulfonyl)pyrrolidin-3-ol

  名称：

  Synthesis of (2R,3S,4S)-4-aryl-3-hydroxyprolinols

  摘要：

  Synthesis of (2R,3S,4S)-4-aryl-3-hydroxyprolinols has been established starting from 2-benzyloxymethylpyrrolidin-2-one framework, which is derived from commercially available trans-(2S,4R)-4-hydroxyproline. The single diastereorner having a trans-cis relative configuration with C-2 and C-3 and C-3 and C-4 is constructed in two one-pot functional group transformations of Grignard addition/dehydration and epoxidation/isomerization as the key steps in moderate yield.
