  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.

• Enzymatic resolution of five membered heterocyclic bromohydrins
  作者：Ángela Villar-Barro、Vicente Gotor、Rosario Brieva

  DOI：10.1016/j.tetasy.2013.04.012

  日期：2013.6

  The lipase catalyzed resolution of trans-3,4-tetrahydrofuran and pyrrolidine bromohydrins by acylation or hydrolysis of their acylated derivatives has been studied. For both heterocycles, the best enantioselectivity was obtained using Candida antarctica lipase B as the catalyst in the hydrolytic processes. The enantiomerically pure bromohydrins are useful intermediates for the preparation of 3,4-fuctionalized cis-heterocycles. (C) 2013 Elsevier Ltd. All rights reserved.

  The lipase catalyzed resolution of cis and trans-3-amino-4-hydroxytetrahydraurans and cis-3-amino-4-hydroxypyrrolidines have been studied. For all the heterocycles, the best enantioselectivity was obtained using Candida antarctica lipases A and B as catalysts in hydrolytic processes. The absolute configuration of the optically pure obtained heterocycles has been assigned. (C) 2014 Elsevier Ltd. All rights reserved.
