Technical Abstract: Lindlar semihydrogenation of the tetrahydropyranyl ether of (E)-7-dodecen-5-yne-1-ol generated a mixture of Z,E-5,7-dodecadienol, over reduction products, (E)-7-dodecenol, Z-5-dodecenol, and a rearrangement product, E-6-dodecenol. Aliquots of the mixture of alcohols were converted to acetate and aldehyde mixtures. Field trapping experiments were conducted against the Siberian moth in Siberia, Russia, using traps baited with a virgin female moth or 100 microgram synthetic mixtures of the aldehyde, alcohols, and acetates alone or in combinations. The tests showed that an 1:1 aldehydes:alcohols blend was as attractive to males as virgin female moths. Additional field tests with combinations of individually pure compounds showed that a binary mixture of Z,E-5-7-dodecadienol and Z,E-5-7-dodecadienal (78:22) alone was a potent male sex attractant for the Siberian moth. The mixture will be useful as a monitoring tool for this destructive defoliator of conifer forests in Asia or as a surveillance too at ports in the USA where the pest might invade.
