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.

Convenient Syntheses of Optically Active Abscisic Acid and Xanthoxin

The Reformatzky reaction of 3-(bromomethyl)crotonate with an optically active epoxycyclohexane aldehyde derivative (3), followed by dehydration, gave the chiral dienoic acid (6) stereospecifically.The product was derived to optically active abscisic acid (1) and xanthoxin (2) successfully.
