Stereochemistry of Female-Specific Normonoterpenes, Sex Pheromone Candidates from the Acarid Mite, Tyreophagus sp. (Astigmata: Acaridae)

抄録

Two normonoterpenes were detected from an unidentified Tyreophagus sp. as new female-specific components. Both planar structures were identified to be 2,6-dimethyl-5-heptenal (1) and 2,6-dimethyl-5-hepten-1-ol (2) by GC/MS co-chromatography with synthetic 1 and 2. The stereochemistry of 2 was determined to be R by a GC analysis with a chiral column, while that of 1 was presumed to be similar to 2 based on the biosynthetic aspects.
