  Asymmetric Syntheses of (−)-1-Deoxymannojirimycin and (+)-1-Deoxyallonojirimycin via a Ring-Expansion Approach

  摘要：

  The asymmetric syntheses of (-)-1-deoxymannojirimycin and (+)-1-deoxyallonojirimycin are described herein. The ring-closing iodoamination of two epimeric bishomoallylic amines to give the corresponding 5-iodomethylpyrrolidines was followed by in situ ring-expansion to give two diastereoisomerically pure (>99:1 dr) cyclic carbonates. Subsequent deprotection gave (-)-1-deoxymannojirimycin and (+)-1-deoxyallonojirimycin as single diastereoisomers in 7.4 and 3.3% overall yield, respectively, from commercially available starting materials.

• Enantio- and Diastereoselective Syntheses of 3-Hydroxypiperidines through Iridium-Catalyzed Allylic Substitution
  作者：Johannes Hoecker、Georg C. Rudolf、Florian Bächle、Steffen Fleischer、Benjamin D. Lindner、Günter Helmchen

  日期：2013.8

  Stereoselective syntheses of 3-hydroxypiperidines have been developed. Key intermediates are N-protected allylamines that are prepared by an enantioselective iridium-catalyzed allylic amination. A subsequent catch and release procedure that involves an epoxidation and base-mediated elimination yields δ-lactams that are suitably functionalized to prepare biologically active 3-hydroxypiperidines. In addition

  The asymmetric syntheses of 2,5-dideoxy-2,5-imino-D-glucitol [(+)-DGDP] and 1,2,5-trideoxy-1-amino-2,5-imino-D-glucitol [(+)-ADGDP] were achieved via the ring-closing iodoamination of an enantiopure bishomoallylic amine, followed by functionalisation of the resultant iodomethyl substituted pyrrolidine. In the case of (+)-DGDP, formation of the corresponding aziridinium ion followed by regioselective ring-opening with H2O gave the desired hydroxymethyl substituted pyrrolidine as a single diastereoisomer (>99:1 dr), with subsequent deprotection giving (+)-DGDP in good yield. Whereas in the case of (+)-ADGDP, displacement of iodide with NaN3 proved to be optimal, giving (+)-ADGDP in good yield after reduction and deprotection. (C) 2014 Elsevier Ltd. All rights reserved.
• Total synthesis of deoxymannojirimycin and d-mannolactam via carbonylation of 5-vinyloxazolidin-2-ones
  作者：Julian G Knight、Kirill Tchabanenko

  日期：2003.1

  The stereoselective synthesis of piperidine alkaloids deoxymannojirimycin and D-mannolactam. from D-serine has been achieved. The key step involves palladium-catalysed decarboxylative carbonylation of a serine-derived 5-vinyloxazolidin-2-one to give 6-(tert-butyldimethylsilyloxymethyl)-3,6-dihydro-1H-pyridin-2-one which was subsequently converted into the title compounds.
