  Catalytic asymmetric synthesis of the Colorado potato beetle pheromone and its enantiomer

  摘要：

  An efficient catalytic asymmetric synthesis of the CPB pheromone [(S)-1,3-dihydroxy-3,7-dimethy1-6-octen-2-one] and its enantiomer was accomplished with 99% ee and in gram quantities from geraniol. The key steps in this procedure involve Sharpless asymmetric epoxidation and recrystallization of the 4-bromobenzoate from the CPB pheromone to improve its enantiomeric purity. Furthermore, the absolute configuration of the CPB pheromone enantiomer was confirmed as (R) for the first time by the X-ray crystallographic structure of its benzoate. (C) 2014 Elsevier Ltd.

  A novel synthesis of the aggregation pheromone of the Colorado potato beetle, Leptinotarsa decemlineata, has been developed based on a Sharpless asymmetric epoxidation in combination with a chemoselective alcohol oxidation using catalytic [(neocuproine)PdOAc]₂OTf₂. Employing this approach, the pheromone was synthesized in 3 steps, 80% yield and 86% ee from geraniol.

  基于Sharpless不对称环氧化和化学选择性醇氧化的组合，利用催化[(neocuproine)PdOAc]₂OTf₂，开发了一种新的合成科罗拉多马铃薯甲虫聚集信息素的方法。采用这种方法，从香叶醇出发，经过3个步骤，得到甲虫聚集信息素，产率为80%，ee为86%。
