Methyl (2E,4Z)-2,4-decadienoate (1), an important pheromone component of Pityogenes calcographus, and its three geometrical isomers (2-4) have been synthesized and obtained in >99percent isomeric purity.Urea inclusion complexes were used in the final purification procedures.Spectroscopic data (MS, (1)H and (13)C NMR) of all four isomers are discussed.A photoisomerization study of the decadienoates is presented.
