Abstract

In this study, using an economical method, we synthesized the (Z)-9-tetradecenyl acetate and (Z)-7-dodecenyl acetate components of the sex pheromone of Spodoptera frugiperda, a major pest of corn and rice crops. Given the expensive starting materials, the method previously developed for the synthesis of these chemicals is unsuitable for bulk production at industrial scales. Moreover, this method necessitates the use of the highly explosive reducing agent lithium aluminum hydride. To reduce production costs, as starting materials, we used the comparatively inexpensive chemicals 1,8-octanediol and 1,6-hexanediol. In addition, for conversion of triple bonds to Z-double bonds, we used Ni(OAc)₂ instead of the more expensive Pt or Pd. The production cost of mass-synthesized products was approximately 50,000 won/g, which represents a considerable saving on the existing method, and can be distributed at a low price. As these products will be available to consumers at economical prices, this method will contribute to the environmentally friendly control of S. frugiperda.
