Paragraph 0063; 0064, (2014/10/28)
Provided is a method for industrially producing a conjugated Z-alken-yn-yl acetate such as Z-13-hexadecen-11-yn-yl acetate which is a sex pheromone component of a pine processionary moth, and an intermediate for the conjugated Z-alken-yn-yl acetate under mild conditions at a high yield. More specifically, provided is a method for producing a conjugated Z-alken-yn-yl acetate (5) comprising the steps of: reacting an ω-halo-2-alkynal (1) with an alkylidene triphenylphosphorane (3) through a Wittig reaction to obtain a conjugated Z-alken-yn-yl halide (4), and acetoxylating the conjugated Z-alken-yn-yl halide (4) into a conjugated Z-alken-yn-yl acetate (5).

Resume : Une synthese courte et stereoselective de la pheromone sexuelle de la Processionnaire du pin : Thaumatopoes pityocamps (Denis et Schiff.) a ete realisee.Cette synthese utilise dans son etape finale une reaction de couplage d'un acetate ω-acetylenique sur un halogenure vinylique dans le benzene en presence de quantites catalytiques de tetrakis(triphenylphosphine)palladium et d'iodure cuivreux.

The synthesis of the major component of the sex pheromone secretion of the processionary moth, Thaumetopoea pityocampa (Denis and Schiff.) (Lepidoptera, Notodontidae), (Z)-13-hexadecen-11-ynyl acetate (1), the corresponding (E)-isomer (2) and the four structurally related model compounds (Z/E,Z,Z)-5,9,13-hexadecatrienyl acetate (3), (Z/E,Z,Z)-3,7,11-hexadecatrienyl acetate (4), (Z/E,E,Z)-7,9,13-hexadecatrienyl acetate (5) and (Z)-7-hexadecen-5-ynyl acetate (6) is described.
