  摘要：

  A synthesis of (+)-cis-disparlure is described starting from racemic 2-hydroxy-dodecan-nitrile (2), which is transformed into the O-protected enantiomerically pure cyanohydrine 4. Grignard-reaction followed by reduction with BH3.(CH3)2S yields the corresponding threo-configurated secondary alcohol 10. After tosylation and cleavage of the MBE-protective-group (+)-cis-disparlure (14) is obtained by treatment with KOH. Mating disruption field tests exhibited a significantly increased effectiveness of (+)-cis-disparlure as compared to the racemic product.
