[origin: WO2022171965A1] 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 absoluta) pheromone comprising: (3E,8Z,11Z)-tetradecatrien-1-yl acetate and (3E,8Z)-tetradecadien-1-yl acetate.
