Abstract:
This review reports different syntheses of deltamethrinic acid, especially those originating from our laboratory. Deltamethrinic acid is a synthetic compound whose structure is inspired from those present in the flower head of the plant Chrysanthemum cinerariifolium. Its ester 'deltamethrin' exhibits an extremely high insecticidal activity (DDTx35.000) and an extremely low toxicity to mammals.
