2. Synthese von (-)-(R)-4-Hydroxy-β-ionon und (-)-(5R,6S)-5-Hydroxy-4,5-dihydro-α-ionon aus (-)-(S)-α-Ionon

, p. 10 - 15 (1980)
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.
Facile lipase catalysed syntheses of (S)-(+)-4-hydroxy-β-ionone and (S)-(+)-4-hydroxy-β-damascone: Chiral flavorants and synthons

Enantioselective syntheses of (S)-(+)-4-hydroxy-β-ionone and (S)-(+)-4-hydroxy-β-damascone have been achieved through pig pancreatic lipase catalysed trans-esterification. These molecules find utility as constituent in fruit-type fragrance and flavor form
Synthesis of (+)-(4S)- and (-)-(4R)11 Z-4-hydroxyretinals and determination of the absolute stereochemistry of a visual pigment chromophore in the bioluminescent squid, Watasenia scintillans

, p. 905 - 908 (2007/10/02)
Synthesis of (+)-(4S)- and (-)-(4R)-11Z-4-hydroxyretinals (4-OH-RALs) 1a and 1b was accomplished from (4S)- and (4R)-4-hydroxy-β-ionones, respectively, to determine the absolute configuration of a visual pigment chromophore in Watasenia scintillans. The C
