Abstract: Compounds, compositions, and methods for controlling an arthropod pest population that employ an eremophilane sesquiterpene parent structure are presented. The compounds have minimal adverse or toxic effects on humans, non-human animals, and the natural environment. The compounds may be isolated from natural sources, semi-synthesized from naturally occurring compounds, or completely synthesized. The compounds may be applied directly to a pest, or the locus of a pest, and function as topical or ingestible toxins. Eremophilane sesquiterpenes 13-hydroxy-valencene, valencene-11,12-epoxide, valencene-13-aldehyde, and nootkatone-1,10-11,12-diepoxide are exemplary compounds.

Abstract: A process for the manufacture of a symmetrical, terminally ring-substituted polyenes by reacting a polyene di(O,O-dialkyl acetal) with a cyclic dienol ether in the presence of a Lewis or Brönsted acid, hydrolyzing the condensation product resulting therefrom and cleaving off alcohol under basic or acidic conditions from the polyene derivative produced at this stage. The novel cyclic dienol ethers, as well as, novel intermediates resulting from the condensation and additional intermediates in this process form further aspects of the invention. The final products are primarily carotenoids, which find corresponding use, e.g., as colorings and pigments for foodstuffs, animal products, etc.
