Abstract
A short synthesis of (E, Z)-7,9-dodecadien-1-yl acetate from propargyl alcohol and 6-bromohexanol via acetylenic-allenic isomerization of the resulting bis-THP-1,9-non-2-yn-diol is described. The field test of several preparations showed that theE,E isomer does not interfere with the biological activity of the pheromone. It was found that the “crude” preparation has higher activity than purified pheromone or virgin females.
