抄録 | Synthesis of both enantiomers of some perfume compounds, and their difference in aroma
characteristics are described. Enantiomeric pairs of methyl jasmonate and its 4,5-didehydro congener, principal components of jasmin absolute, were prepared from the corresponding commercially available racemates using lipase-catalyzed optical resolution. The E-value for the reaction is as high as 370. The nature-identical isomers produced superior aroma activity relative to unnatural ones. Racemic lavandulol from a commercial source, was also resolved using several enzymatic transesterifications followed by hydrolysis with PPL. Odor evaluation revealed that the nature-identical isomer should play a key role in lavender oil. Cis-α-irone and cis-γ-irone, used as important violet components for perfumery, were synthesized in optically active forms through fractional crystallization of the diastereomeric salts with α-phenethylamine. The nature-identical irones also had better floral characteristics like ionone.
