The total synthesis of (S)-(+)-ferrulactone (2), one of several synergistic aggregationpheromones produced by male flatgrainbeetles, Cryptolestes ferrugineus (Stephens) was achieved in a five-step synthesis in very high optical purity (>99% ee) and 17.5% chemical yield, starting from (S)-(+)-methyl-8-hydroxynonanoate (5) and a three-carbon Wittig reagent 11. The nine-carbon bifunctional chiron 5
