  描述：

  1-Cbz-3-azido-4-hydroxypyrrolidine 在 sodium hydride 、 三乙胺 、 三苯基膦 作用下， 以 四氢呋喃 、 正己烷 、 水 、 N,N-二甲基甲酰胺 为溶剂， 反应 25.0h， 生成 1-Cbz-3-[(tert-butoxycarbonyl)methylamino]-4-methoxypyrrolidine

  名称：

  Chemoenzymatic synthesis of (3R,4S)- and (3S,4R)-3-methoxy-4-methylaminopyrrolidine

  摘要：

  An efficient and a convenient enantio selective synthesis of (3R,4S)-3-methoxy-4-methylaminopyrrolidine has been carried out by a lipase-mediated resolution protocol. This method describes the preparation of (+/-)-l-Cbz-cis-3-azido-4-hydroxypyrrolidine starting from commercially available diallylamine followed by ring-closing metathesis (RCM) via S(N)2 displacement reactions. Pseudomonas cepacia lipase immobilized on diatomaceous earth (Amano PS-D) provides (3R,4S)-11 and (3S,4R)-12 in an excellent enantiomeric excess. (c) 2006 Elsevier Ltd. All rights reserved.
