Abstract
We report the first synthesis of the two components of the female sex pheromone of Matsucoccus josephi (2E,4E,8E)-4,6-dimethyl-2,4,8-decatri en-7-one (1) and (2E,4Z,8E)-4,6-dimethyl-2,4,8-decatrien-7-one (2) uti lizing the Reformatzky and Wittig reactions as key steps. A mixture of 1 and 2 and the separate isomers were bioassayed in a pine forest ind icating that E isomer 1 is much more active than 2 and is also a kairo mone for a predator.
