  Radical cyclisation reactions leading to polyhydroxylated cyclopentane derivatives: synthesis of (1R,2R,3S,4R)- and (1S,2S,3R,4S)-4-hydroxyethylcyclopentane-1,2,3-triol

  摘要：

  The tetraol (-)-1 has been prepared from a derivative of (D)-allose 3. The stereoselective carbocyclization reaction (8 double line arrow pointing right 11) formed the key step in this sequence. The enantiomeric cyclopentane derivative(+)-1 was also prepared from compound 3.In this synthesis the cyclization of compound 18 to provide the carbocycle 19 features as the critical carbon-carbon bond forming reaction.
