In 1973 when I began the synthesis of (S)-2, almost nothing was known about the absolute configuration of chiral and non-racemic pheromones, and it was not even clear whether enantiomeric composition would play a role at all in pheromonal communications.
The absolute configuration of the natural pheromone can thus be clarified and established.
