Abstract The synthetic route to (2E,4E,6E)-5-ethyl-3-methyl-2,4,6-nonatriene, the aggregation pheromone of the Freeman sap beetle, Carpophilus freemani Dobson (Coleoptera: Nitidulidae), has been improved in terms of 6E isomer selectivity by the use of tetra-n-propyltriphenylphosphonium bromide in the final Wittig reaction. Separation of the 6E-isomer from undesired 6Z-isomer can be accomplished on a preparative scale by HPLC using a silica column with hexane as the elution solvent. This… CONTINUE READING
