The pheromone of Phtheochroacranaodes (Lepidoptera: Tortricidae) was identified as (3E,5Z)-3,5-dodecadienyl acetate (5) by GC-MS analysis of female gland extracts and field trapping of males with synthetic compound.

The female sexpheromone (3E,5Z)-3,5-dodecadienyl acetate of Phtheochroacranaodes was regio- and stereo-selectively synthesized using electrophilic trimethylchlorostannane-induced rearrangement of lithium 1-octynylborate as the main process

(3E, 5Z)-3,5-Dodecadienyl acetate, the female sexpheromone of Phtheochroacranaodes, was regio and stereo-selectively synthesized from 1-octyne and (E)-4bromo-3-buten-1-ol by using Pd(PPh3)4, CuI and piperidine to afford the enyne (5). Further elaboration afforded the target pheromone. The synthetic pheromone was identified with the natural product by its MS and IR, data GLC retention time and biological

Practical convergent syntheses of the four geometrical isomers of 3,5-dodecadienyl acetate are presented. These substances have been characterized by NMR and mass spectroscopy. (3E,5Z)-3,5-Dodecadienyl acetate is the main female sex pheromone component of the leaf roller Bonagota cranaodes, which is an important insect pest in apples in South America.The isomeric 3,5-dodecadienyl acetates, as pure isomers and in defined mixtures, have been used as trap lures for Eying insects in field screening experiments in Lithuania. Although no insects were found in the control traps, the numbers of males caught in the baited traps were not high enough to be statistically significant.

Provided is a method for preparing (E3,Z5)-3,5-alkadienyl acetate and (E3,Z5)-3,5-dodecadienyl acetate which is a sex pheromone of Brazilian apple leafminer. Specifically, provided is a method for preparing (E3,Z5)-3,5-alkadienyl acetate, comprising steps of hydrolyzing 5,5-diethoxy-(Z3)-3-pentenyl methoxymethyl ether in the presence of an acid to obtain 4-formyl-(E3)-butenyl methoxymethyl ether; reacting the 4-formyl-(E3)-butenyl methoxymethyl ether with alkylidene triphenylphosphorane in accordance with the Wittig reaction to obtain (E3,Z5)-3,5-alkadienyl methoxymethyl ether; and obtaining (E3,Z5)-3,5-alkadienyl acetate using the (E3,Z5)-3,5-alkadienyl methoxymethyl ether as a starting substance.
