Synthesis of loliolide, actinidiolide, dihydroactinidiolide, and aeginetolide via cerium enolate chemistry

(Chemical Equation Presented) Loliolide, aeginetolide, actinidiolide, and dihydroactinidiolide were synthesized in racemic form from a single common intermediate, prepared through the 1,2 addition of the cerium enolate of ethyl acetate to 2,6,6-trimethylcylohexenone.

Stereocontrolled syntheses of carotenoid oxidative metabolites, (-)-loliolide, (-)-xanthoxin, and their stereoisomers

We achieved the stereocontrolled syntheses of (-)-loliolide, (-)-xanthoxin, and their stereoisomers from (+)- or (-)-3-alkoxy-6-hydroxymethyl-1,1,5-trimethylcyclohexene through the corresponding syn and anti-epoxides, respectively, which were obtained by utilizing the highly diastereoselective Sharpless asymmetric epoxidation or mCPBA oxidation.

Carotenoids and Degraded Carotenoids, VIII. Synthesis of (+)-Dihydroactinidiolide, (+)- and (-)-Actinidiolide, (+)- and (-)-Loliolide as well as (+)- and (-)-Epiloliolide

Enantiomerically pure (S)-2,4,4-trimethyl-2-cyclohexen-1-ol (1) was efficiently converted into four degraded lactonic carotenoids: (S)-dihydroactinidiolide (5), (S)-actinidiolide (9), (6S,7aR)-loliolide (11) and (6S,7aS)-epiloliolide (12). (R)-Actinidioli
