Abstract
The present invention provides methods for synthesizing pyrethroid compounds. The methods include forming a first reaction comprising an olefin and an allethrolone-type unsaturated alcohol under conditions sufficient to form a metathesis product and converting the metathesis product to the pyrethroid. Methods of the invention can be used to prepare compounds including pyrethrin I, cinerin I, jasmolin I, pyrethrin II, cinerin II, and jasmolin II as well as other synthetic pyrethroid compounds. Insecticidal compositions and methods for controlling insects are also described.
