Neodiprion sertifer

Neodiprion sertifer Virgin female-produced male attractant Acetate propanoate of (2S,3S,7S)-3,7-dimethyl-pentadecan-2-ol 1. Depending on the population, the (2S,3R,7R)-isomer of the acetate can be benign, inhibitory, or necessary. [27,40,41]... 

The field response of the European pine sawfly, Neodiprion sertifer, to the acetate of (2S,3S,7S)-3,7-dimethylpentadecan-2-ol 1 and the effect of the (2S,3R,7R)-iso-mer was studied from Japan in the east to Canada in the west. The addition of the (2S,3R,7R)-isomer was benign in Japan, inhibitory in Europe with the inclusion of as little as 1%, and its presence essential in Siberia. These findings will allow for the development of a more efficient N. sertifer monitoring scheme without having to determine the stereochemistry produced in each population [27].

Reaction of (5)-2-methy1decan-1-y1- 1ithiurn (76) with (3s,4s)-3, 4-dimethyl-Y-butyrolactone (75) has been used to prepare (2s,35,7s)-3,7-dimethylpentadecan-2-ol (77)This alcohol was converted to the acetate and propionate,which are potential pheromones of the European pine sawfly, Neodiprion sertifer. The chiral lactone (75) was obtained from (2S,3S)-trcms-epoxybutane and dimethyl malonate.
