1-Phenylethanol is the organic compound with the formula C6H5CH(OH)CH3. It is one of the most commonly available chiral alcohols. It is a colorless liquid with a mild gardenia-hyacinth scent.[4]
Phenylethanol is an aromatic alcohol, it has the role of mouse metabolite. It is a natural product and is found in Cichorium endivia, Castanopsis cuspidata and other organisms.[6]
Natural occurrence
1-Phenylethanol is found in nature as a glycoside, together with its hydrolase β-primeverosidase in tea (Camellia sinensis) flowers.[7] It is also reportedly present in cranberries, grapes, chives, Scottish spearmint oil, cheeses, cognac, rum, white wine, cocoa, black tea, filbert, cloudberries, beans, mushrooms, and endives.[8]
Synthesis
Racemic 1-phenylethanol is produced by the reduction of acetophenone by sodium borohydride. Alternatively, benzaldehyde can be reacted with methylmagnesium chloride or similar organometallic compounds to afford racemic 1-phenylethanol.
Asymmetric hydrogenation of acetophenone by Noyori catalysts proceeds quantitatively (50 atm H2, room temperature, minutes) in >99% e.e.[9]
