α-卤代四甲基环己酮及其与（2,3,4,4-四甲基环戊基）甲基羧酸酯的制备方法
摘要：
本发明提供一种制备暗色粉蚧(OMB)的性信息素(正/反)(2,3,4,4-四甲基环戊基)甲基乙酸酯的方法。该方法包括：对α-卤代四甲基环己酮进行法沃尔斯基重排以获得2,3,4,4-四甲基环戊烷化合物(2)的步骤；将所述化合物(2)还原以获得(2,3,4,4-四甲基环戊基)甲醇(3)的步骤；和对所述化合物(3)进行酰化以获得(2,3,4,4-四甲基环戊基)甲基羧酸酯化合物(4)的步骤。
摘要（英）：

The present invention provides a method for the preparation of a sex pheromone of Obsucure Mealy bug (OMB), (plus/minus) (2,3,4,4-tetramethycyclopentyl)methyl acetate. The method comprises a step of subjecting alpha-halotetramethylcyclohexanone to a Favorskii rearrangement to obtain a 2,3,4,4-tetramethylcyclopentane compound (2), a step of subjecting said compound (2) to reduction to obtain (2,3,4,4-tetramethylcyclopentyl)methanol (3) and a step of subjection said compound (3) to acylation to obtain a (2,3,4,4-tetramethylcyclopentyl)methyl carboxylate compound (4).
