Discovery of Aromatic Components with Excellent Fragrance Properties and Biological Activities: β-Ionols with Antimelanogenetic Effects and Their Asymmetric Syntheses
high optical purity by lipase-catalyzedkineticresolution of the racemates. It was found that all these enantiomers had different characteristic favorable scents and high antimelanogenetic effects. The absolute configuration and the enantiomer ratios of dihydro-β-ionol in the aromatic components of Osmanthus flower and of Hakuto peach were determined. The asymmetric synthesis of (R)-dihydro-β-ionol
