Carotenoids and related polyenes. Part 7. Total synthesis of crassostreaxanthin B applying the stereoselective rearrangement of tetrasubstituted epoxides

(3R,3′S)- and (3R,3′R)-Crassostreaxanthin B isomers are synthesized by application of the stereoselective rearrangement of tetrasubstituted epoxides 5a,b. As a result, the absolute configuration at C-3′ of 1 is determined to be S.
