  • Patent number: 9919994
    Abstract: A method for the preparation of a sex pheromone of Obscure Mealy bug (OMB), (±)(2,3,4,4-tetramethycyclopentyl) methyl acetate includes a step of subjecting alpha-halotetramethylcyclohexanone to a Favorskii rearrangement to obtain a 2,3,4,4-tetramethylcyclopentane compound (2), a step of subjecting the compound (2) to reduction to obtain (2,3,4,4-tetramethylcyclopentyl)methanol compound (3) and a step of subjection the compound (3) to acylation to obtain a (2,3,4,4-tetramethylcyclopentyl)methyl carboxylate compound (4).

  • Patent number: 9822050
    Abstract: Provided are a terminal conjugated trienal acetal compound useful as an intermediate for producing a terminal conjugated trienal compound, and a method for producing a terminal conjugated trienal compound through deprotection of the terminal conjugated trienal acetal compound. More specifically, provided are a terminal conjugated trienal acetal compound represented by General Formula (1); a method for producing a (Z,E)-terminal conjugated trienal acetal compound, the method comprising the step of: reacting a phosphonium salt represented by General Formula (7) with (E)-2,4-pentadienal through Wittig reaction to obtain a (Z,E)-terminal conjugated trienal acetal compound represented by General Formula (3); and a method for producing a terminal conjugated trienal compound, the method comprising the step of: deprotecting the terminal conjugated trienal acetal compound represented by General Formula (1) to obtain a terminal conjugated trienal compound represented by General Formula (2).

  • Patent number: 9725400
    Abstract: Provided is a geometrically selective method for producing (±)-(E)-2-isopropyl-5-methyl-3,5-hexadienyl acetate, which is a sex pheromone of grape pineapple mealybug (GPMB). Specifically provided is a method for producing a an (E)-2-isopropyl-5-methyl-3,5-hexadienyl carboxylate compound (4), the method comprising the steps of: dehydrating a 3-hydroxy-2-isopropyl-5-methyl-4-hexenoate compound (1) to obtain an (E)-2-isopropyl-5-methyl-3,5-hexadienoate compound (2); reducing the alkoxycarbonyl group of the compound (2) to obtain (E)-2-isopropyl-5-methyl-3,5-hexadienol (3); and esterifying the compound (3) to obtain the compound (4).
