Method for preparation of Octadecadienyl acetate as major sex pheromone of cherry tree borer, Synanthedon bicingulate
-
Paragraph 0079; 0084-0086, (2018/06/26)
The present invention relates to a method for producing a sex pheromone of cherry tree borer (Synanthedon bicingulata) in an attempt to control the same. More specifically, provided is a method for stereoselectively producing high purity (3E,13Z)- octadecadienyl acetate and (3Z,13Z)-octadecadienyl acetate respectively which are major sex pheromones of cherry tree borer from a cheap starting material in an efficient, simple, and economically feasible way.COPYRIGHT KIPO 2018

(equation presented) A new, convergent synthesis of (E,Z)-2,13-octadecadienyl acetate (1) and (E,Z)-3,13-octadecadienyl acetate (2), the two key components of the leopard moth Zeuzera pyrina, from 2-chloromethyltetrahydrofuran in good overall yields and stereomeric purity is reported. The synthesis of both components utilizes the common intermediate sulfone 12 as a convenient building block to be coupled with iodoacetylenic derivatives 9 or 17 in the key step.

The Wittig-Horner reaction of ethoxycarbonylmethylenetriphenylphosphorane or ethyl diethylphosphonoacetic acid with cis-11-hexadecenal and the modified Knoevenagel reaction of this aldehyde with malonic acid gave the ethyl ester of trans-2,cis-13-octadecadienoic acid and trans,cis-13-octadecadienoic acid, which upon reduction and acetylation were converted into trans-2,cis-13- and trans-3-cis-13-octadecadien-1-yl acetates, which are components of the sex pheromone of Synanthedon tipuliformis (Lepidoptera, Sisiidae).
