History
The activity of this pheromone was first described in 1952, but it was not until 25 years later that Persoons et al. reported the gross structure of periplanones A and B. The stereochemical configuration and first total synthesis were reported by W. Clark Still's group at Columbia University in 1979.{{cite book |title= Classics in Total Synthesis|last= Nicolaou|first= K. C.|author-link=K. C. Nicolaou |author2=E. J.
