The main components of the sex pheromone of Plutella xylostella (L.) were synthesized from 10-undecen-1-ol and iodopentane as starting materials. Firstly, Z11-16:OH was obtained by benzoylation of 10-undecen-1-ol, then hydroboration with 9-borabicyclo[3.3.1]nonane (9-BBN) followed by oxidation, further oxidation with pyridinium chlorochromate (PCC), and then by Wittig reaction and debenzoylation in a total yield of 53% for 5 steps. Z11-16:Ald and Z11-16:Ac were prepared from Z11-16:OH by oxidation or acetylation. Their structures were confirmed by NMR, IR and MS techniques. This is a good method with the advantages of short synthetic routes, normal operation and higher yield as compared with the reported methods.

Key words: Plutella xylostella (L.), sex pheromone, synthesis, Wittig reaction
