File PreviewThe following is a total synthesis of the pheromone of the western pine beetle. Suchsyntheses are interesting both because of the organic chemistry, and because of the possibility ofusing species specific insecticides, rather than broad band insecticides. Provide the reagents foreach step. There is some chemistry from our most recent chapter in this synthesis, but othersteps are review from earlier chapters.
