  Enantioselective synthesis of α-benzyloxy-ω-alkenals: application to the synthesis of (+)-exo-brevicomin, (+)-iso-exo-brevicomin, and (−)-isolaurepan

  摘要：

  The enantioselective synthesis of alpha-benzyloxy aldehydes containing a terminal alkene was carried out from chiral Pool L-(+)tartaric acid by employing the stereoselective reduction of a 1,4-diketone as the key step. The synthetic utility of these aldehydes was demonstrated in the synthesis of pine beetle pheromones (+)-exo-brevicomin, (+)-iso-exo-brevicomin and a formal synthesis of 2,7cis-disubstituted oxepane (-)-isolaurepan.
