标题 :Process or synthesis of (3S)- and (3R)-3-hydroxy-beta-ionone, and their transformation to zeaxanthin and beta-cryptoxanthin

摘要:Disclosed is a process for the synthesis of (3R)-3-hydroxy-β-ionone and its (3S)-enantiomer in high optical purity from commercially available (rac)-α-ionone. The key intermediate for the synthesis of these hydroxyionones is 3-keto-α-ionone ketal that was prepared from (rac)-α-ionone after protection of this ketone as a 1,3-dioxolane. Reduction of 3-keto-α-ionone ketal followed by deprotection, lead to 3-hydroxy-α-ionone that was transformed into (rac)-3-hydrox-β-ionone by base-catalyzed double bond isomerization in 46% overall yield from (rac)-α-ionone. The racemic mixture of these hydroxyionones was then resolved by enzyme-mediated acylation in 96% ee. (3R)-3-Hydroxy-β-ionone and its (3S)-enantiomer were respectively transformed to (3R)-3-hydroxy-(β-ionylideneethyl)triphenylphosphonium chloride [(3R)-C 15 -Wittig salt] and its (3S)-enantiomer [(3S)-C 15 -Wittig salt] according to known procedures. Double Wittig condensation of these Wittig salts with commercial available 2,5- dimethtylocta-2,4,6-triene-1,8-dial provided all 3 stereoisomers of zeaxanthin. Similarly, (3R)-C 15 -Wittig and its (3S)-enantiomer were each coupled with β-apo-12′-carotenal.
