| Abstract: | Details are given for the determination of the enantiomeric composition of several insect pheromone alcohols. The two methods used in the determination were: formation of the derivative with (+)- -methoxy--trifluoromethylphenylacetyl chloride and the use of chiral lanthanide shift reagents. The five alcohols studied and their enantiomeric compositions are: sulcatol fromGnathotrichus sulcatus 65 35 (+)/(–),trans-verbenol fromDendroctonus frontalis 6040 (+)/(–), 4-methyl-3-heptanol fromScolytus multistriatus 100% (–), seudenol fromDendroctonus pseudotsugae 5050 (+)/(–), and ipsdienol fromIps pini (Idaho) 100% (–). Determinations were done on 50–500  g substrate. |
