“…These three synthetic fragrances posses floral and fruity notes (rose, lily‐of‐the‐valley, citrus) and are commercially available in racemic form. An efficient asymmetric synthesis of Phenoxanol, as well as its transformation in Citralis and Nitrile Citralis, was reported by Matteoli14 who also reported the odor profiles of the single enantiomers, showing a significant difference in odor threshold between compounds with opposite configuration and, for Phenoxanol, also in olfactorily notes. Such a synthetic procedure was based on the asymmetric hydrogenation of ( Z )‐ or ( E )‐allylic alcohols with Ru‐2,2′‐bis(diphenylphosphino)‐1,1′‐binaphtalene (BINAP) complexes giving products in high enantiomeric excesses, but requiring high hydrogen pressure (100 atm) and long reaction times (48 h) for the complete conversion.…”
