The absolute configuration of the chiral 4-hydroxy-β-ionones and 5-hydroxy-4,5-dihydro-α-ionones has been determined by chemical connection with (-)-(S)-α-ionone i.e. by stereoselective epoxidation of the latter, followed by base catalyzed opening of the epoxide as well as by its hydride reduction.
