  名称：

  Synthesis of three branched iminosugars [(3R,4R,5S)-3-(hydroxymethyl)piperidine-3,4,5-triol, (3R,4R,5R)-3-(hydroxymethyl)piperidine-3,4,5-triol and (3S,4R,5R)-3-(hydroxymethyl)piperidine-3,4,5-triol] and a branched trihydroxynipecotic acid [(3R,4R,5R)-3,4,5-trihydroxypiperidine-3-carboxylic acid] from sugar lactones with a carbon substituent at C-2

  摘要：

  Homochiral piperidines containing a quaternary carbon branch at C-2 of the piperidine ring may be made from readily available carbohydrate lactones containing a branched 2-C-hydroxymethyl substituent. This gives an easy access to the branched iininosugars. In particular a trihydroxypipecolic acid analogue, (3R,4R,5R)-3,4,5-trihydroxypiperidine-3-carboxylic acid, has been synthesised efficiently from the starting material D-ribose and (35,4R,5S)-3-(hydroxymethyl)piperidine-3,4,5-triol was found to be a specific inhibitor of alpha-D-glucosidase from Bacillus Stearothermophilus with an IC50 value of 93 mu M.
