  Short and efficient synthesis of (2S,3R,4R,5R) and (2S,3R,4R,5S)-tetrahydroxyazepanes via the Henry reaction

  摘要：

  The Henry reaction with the easily available alpha-D-xylo-pentodialdose afforded a diastereomeric mixture of nitroaldoses with the alpha-D-gluco- and beta-L-ido-configuration, respectively, in good yield. When n-BuLi was used as the base, the reaction afforded the alpha-D-gluco-nitroaldose as the only product. The reduction of the nitro group in the alpha-D-gluco- and beta-L-ido-nitroaldoses, removal of the protecting groups and intramolecular reductive cyclo-amination afforded the corresponding (2S,3R,4R,5R) and (2S,3R,4R,5S) tetrahydroxyazepanes.

• One-pot synthesis of vicinal aminoalkanols from sugar aldehydes
  作者：Raquel G. Soengas、Artur M.S. Silva

  日期：2013.4

  A novel synthetic method of carbohydrate derived vicinal aminoalcohols, from sugar aldehydes and bromonitroalkanes, has been developed. It involves an indium-catalyzed one-pot Henry reaction and nitro group reduction, and proceeds with a remarkably high anti-selectivity. The reaction of the intermediate aminoalcohols with alkylating agents furnished the corresponding carbohydrate-based tertiary aminoalcohols

  日期：2010.9

  A novel method for the preparation of 2-nitroalkan-1-ols by an indium-promoted reaction of bromonitromethane with a variety of aldehydes is reported. The reaction was also performed with 2-bromo-2-nitropropanes to afford 2,2-dialkyl-2-nitroalkan-1-ols. The use of chiral sugar-derived aldehydes furnished the corresponding 2-nitroalkan-1-ols with excellent stereoselectivity. The utility of the novel

• Synthesis of Sugar-Derived 2-Nitroalkanols via Henry Reaction Promoted by Samarium Diiodide or Indium
  作者：Humberto Rodríguez-Solla、Raquel Soengas、Noemí Alvaredo

  DOI：10.1055/s-0031-1290441

  日期：2012.9

  We present herein an improved synthesis of nitro sugars, consisting of a Henry-type reaction of bromonitromethane and sugar aldehydes. The reaction can be promoted by either SmI2 or indium metal, yielding in both cases high yields and good diastereoisomeric ratios. However, while the SmI2-promoted reaction is very sensitive to steric factors and only gives satisfactory results with bromonitromethane, the indium-mediated reaction is not subjected to this limitation, giving excellent results with bromonitromethane as well as more hindered bromonitroalkanes.
