  • NOVEL METHOD FOR MANUFACTURING TOMATO LEAFMINER PHEROMONE COMPONENTS
    Publication number: 20240140902
    Abstract: The present invention relates to a method for synthesising a pheromone of general formula selected from the group comprising compounds (I) and (I?), alone or in admixture: (I) (I?) comprising reacting (2E)-pentene-1,5-diyl diacetate with at least one Grignard reagent in the presence of a copper-based catalyst. The method according to the invention is particularly applicable to the selective synthesis of tomato leafminer (Tuta absolute) pheromone comprising: (3E,8Z,11Z)-tetradecatrien-1-yl acetate and (3E,8Z)-tetradecadien-1-yl acetate.

  • Novel Composition Of 7,9-Dodecadienyl-1-Acetate Isomers And Process For Production Thereof
    Publication number: 20230234977
    Abstract: The present invention relates to a process for preparing a mixture M1 of enol phosphate isomers devoid of (E,E) isomer and comprising at least 98% of (E,Z) isomer, at least 0.1% of (Z,Z) isomer and at least 0.1% of (Z,E) isomer, comprising bringing a mixture of isomers of said enol phosphate comprising a detectable amount of (E,E) isomer into contact with a hydrolysable dienophile in an organic solvent, followed by base hydrolysis of the medium obtained and elimination of the adduct formed, in order to obtain the mixture M1 devoid of (E,E) isomer.

  • NEW STABLE FORMULATIONS OF 1-Z-BROMOALK-1-ENE COMPOUNDS AND USE THEREOF IN THE MANUFACTURE OF PHEROMONES
    Publication number: 20220259134
    Abstract: The present invention concerns new stable compositions of 1-Z-bromoalk-1-ene compounds of general formula (A). These compositions are characterized in that they also comprise either at least one cyclic ether compound comprising between 4 and 6 carbon atoms, or at least one ether of general formula (B) in which R1 and R2 are identical or different and selected from the group consisting of: a linear or branched alkyl group containing 1 to 8 carbon atoms.
