and attacks spruces. The contact sex pheromone of this pest, (S)-11-methyl-heptacosane, and its enantiomer were synthesized via Evans’ chiral auxiliaries. The key steps of this approach included acylation of carboxylic acid, diastereoselective methylation of oxazolidinone amide, and Wittig coupling of the aldehyde with chiral phosphonium salt. The synthetic pheromones would have potential utility in
Tetropium fuscum是一种有害的森林害虫,会攻击云杉。该害虫的接触性信息素( S )-11-甲基-庚烷及其对映异构体是通过Evans的手性助剂合成的。该方法的关键步骤包括羧酸的酰化、恶唑烷酮酰胺的非对映选择性甲基化以及醛与手性鏻盐的 Wittig 偶联。合成的信息素将在控制这种害虫方面具有潜在的用途。
