A convergent, general synthesis of (2E,4E)-4,6,10,12-tetramethyltrideca-2,4-dien-7-one (matsuone, 1) and five closely related analogs (2–6), which serve as sex pheromone components of female Matsucoccus pine scales, is described. The aldehydes 8a and 8b were obtained via a reaction sequence in which the key step is a [2,3]-Wittig sigmatropic rearrangement of the oxazoline ether of bisallylic tertiary
(2 E,4 E)-4,6,10,12-tetramethyltrideca-2,4-dien-7-one(matsuone,1)和五个密切相关的类似物(2-6)的会聚一般合成作为女性松球菌松鳞的性信息素成分,已被描述。醛8a和8b是通过反应序列获得的,其中关键步骤是双烯丙基叔醇11的恶唑啉醚的[2,3]-Wittigσ重排。生成的仲醇可提供信息素1–6。
