Enzyme-mediated synthesis of (R)- and (S)-α-ionone

Diastereoisomeric enrichment through fractional crystallisation of 4-nitrobenzoate derivatives of α-ionol, and enantioselective enzyme-mediated reactions of α-ionol and α-ionol acetate, were usefully combined to optimise two different procedures to enantiopure (S)- and (R)-ionone.
