    Description / Table of Contents: Pheromone, II. Synthesis of cis-Tetradec-9-enyl AcetateThe Wittig-reaction between 9-acetoxynonanal (2) and triphenyl(pentylidene)phosphorane (1) in salt-free solution leads to the formation of cis-tetradec-9-enyl acetate (3). 2 was obtained in two steps starting from oleic alcohol or in eight steps starting from nonanedioic acid. The synthetic pheromone 3 shows strong activity in the electrophysiological test in the case of various species of Noctuidae (Lepidoptera).
    Notes: Die Wittig-Reaktion zwischen 9-Acetoxy-nonanal (2) und einer salzfreien Lösung von Triphenyl-pentyliden-phosphoran (1) führt zum Essigsäure-[cis-tetradecen-(9)-yl-ester] (3). 2 erhält man ausgehend von Oleinalkohol in 2 Stufen oder ausgehend von Azelainsäure in 8 Stufen. Das synthetische Pheromon 3 erwies sich im elektrophysiologischen Test bei verschiedenen Noctuiden-Arten der Ordnung Lepidoptera als hoch wirksam.

    Description / Table of Contents: Pheromones, VII. Synthesis of 1-Substituted (Z)-9-AlkenesA general method to prepare 1-substituted (Z)-9-olefines is described, which allows the synthesis of pheromones and the systematic variation of their structures. The physiological activity of some of the compounds synthesized by this route is discussed.
    Notes: Es wird eine allgemeine Methode zur Darstellung von 1-substituierten (Z)-9-Olefinen durch stereoselektive Wittig-Reaktion beschrieben. Sie ermöglicht die Synthese von Pheromonen und die systematische Abwandlung ihrer Strukturen. Die physiologische Wirksamkeit einiger auf diesem Wege erhaltener Verbindungen wird diskutiert.
