Antifeedants, or food deterrents, are substances that, by acting on the sense of taste of insects, entirely or partially inhibit their feeding and can be used to reduce the population of harmful species. Antifeedants have the advantage of low toxicity and high selectivity towards selected groups of pests, providing an alternative to the classically used insecticides, which usually have a broad spectrum of action and greater toxicity, even towards vertebrates. Among their numerous activities, lactones can exhibit antifeedant properties. However, the use of natural lactones as antifeedants is limited due to their low isolation yields from natural sources and complex chemical synthesis. Therefore accesible synthetic compounds are of great interest. This work presents the synthesis pathways and the deterrent activities of the lactones obtained in convenient transformations, often from natural terpene precursors.
