Biochemical Preparation of Optically Active 4-Hydroxy-β-ionone and Its Transformation to (S)-6-Hydroxy-α-ionone

The preparation of 4-hydroxy-β-ionone of high enantiomeric excess was achieved via lipase-catalyzed transesterifaction of the corresponding racemate as the key-step.Starting from its (R)-enantiomer, (S)-6-hydroxy-α-ionone, an important intermediate for synthetic abscisic acid analogs, was synthesized.

Synthesis and Chirality of the Enantiomeric 6-Hydroxy-α-ionones and of cis- and trans-5,6-Dihydroxy-5,6-dihydro-β-ionones

We describe the synthesis of (-)-(5R,6S)-5,6-dihydroxy-5,6-dihydro-β-ionone (10) and (+)-(5S,6S)-5,6-dihydroxy-5,6-dihydro-β-ionone (12).The absolute configuration of these compounds has been established by correlation with (R)-4-hydroxy-β-ionone (1).
