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).
本发明提供了一种制备Obsucure Mealy bug(OMB)性信息素--(加/减)(2,
3,4,4-四甲基环戊基)甲基
乙酸酯的方法。该方法包括以下步骤:将α-卤代四甲基
环己酮进行 Favorskii 重排,得到 2,3,4,4-四
甲基环戊烷化合物(2);将所述化合物(2)进行还原,得到(2、
3,4,4-四甲基环戊基)
甲醇(3),再将所述化合物(3)酰化,得到(2,
3,4,4-四甲基环戊基)甲基
羧酸化合物(4)。
