Abstract
New and cheap synthetic method found for the preparation of lepidopteran pheromones which include navel orangeworm pheromones. The structure of these types of pheromones contains pentaene groups which are easier to be prepared through our pathway. These pheromones were synthesized by using directives ozonolysis of cyclonona-1,4,7-triene compounds, which are then converted to a Wittig salt which is using Wittig reaction for coupling with an aldehyde which prepared as a second product from the same ozonolysis step. These synthetic methods involve novel, efficient, and environmentally benign steps.
Keywords: Sex pheromones, (3Z,6Z,9Z,12Z,15Z)-pentacosapentaene, (3Z,6Z,9Z,12Z,15Z)-tricosapentaene, orangeworm and Ozonolysis
