Abstract
|
|
|
|
Synthesis and biological activity test are described for the (Z)-11-hexadecen-1-ol, (Z)-11-hexadecen-1-yl acetate, and (Z)-11-hexadecen-l-al, the sex pheromone of the diamond back moth, Plutella xylostella L.. Lithium acetylide was alkylated with 10-bromodecan-1-ol THP ether to give 11-hexadecyn-l-ol THP ether. 11-Hexadecyn-l-ol THP ether was stereoselectively reduced over Pd/BaSO4to yield (Z)-11-hexadecen-l-ol THP ether, which was in turn deprotected to provide (Z)-11-hexadecen-l-ol. (Z)-11-Hexadecen-l-ol was acetylated and oxidized to afford (Z)-11-hexadecen-1-yl acetate and (Z)-11-hexadecen-l-al, respectively. Biological activity test of the synthetic compounds, (Z)-11-hexadecen-l-ol, (Z)-11-hexadecen-1-yl acetate, and (Z)-11-hexadecen-l-al in the ratio of 0.1 : 5 : 5 was tested in the field using polyethylene capsules as containers. The numbers of moth trapped with pheromone vials were counted.
