  摘要：

  Enantiomerically pure 1,2-diols bearing optionally syn or anti configurated secondary hydroxylic groups are synthesized from acetal-protected cyanohydrins. After resolution of the diastereomers the cyanohydrins are converted into alpha-alkoxy-ketones by Grignard-reaction followed by reduction using common chelating or non-chelating agents. Among others syntheses of enantiomerically pure pheromones, endo-Brevicomin, exo-Brevicomin and Dispalure are given as examples.
