Synthesis and Chirality of the Enantiomeric 6-Hydroxy-α-ionones and of cis- and trans-5,6-Dihydroxy-5,6-dihydro-β-iononesWe 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).Therefore, by comparison, the 5,6-dihydroxy-5,6-dihydro-β-ionone recently isolated from Rehmannia glutinosa var. purpurea by Endo et al.[4] has the (5R,6R)-configuration ((-)-12). The same holds for the 5-β-D-glucopyranoside (15) isolated from Aeginetia indica var. gracilis.
