Stereocontrolled Synthesis of the Sex Pheromones of the Green Stink Bug

Abstract
The four diastereoisomeric 3′,4′-epoxides of (Z)-α-bisabolene, (+)-1, (+)-2, (-)-1 and (+)-2, have been synthesized by stereocontrolled sequences. Comparisons with natural materials collected from the stink bug Nezara viridula revealed that the pheromone blend of this species contains (+)-1 or (-)-2 as major epoxide and (+)-2 or (-)-1 as minor epoxide in varying ratios depending on the geographical site of collection.
