Abstract
The first total syntheses of amarouciaxanthin A and B (C40) via the stereoselective Wittig reaction of C15-allenic and C15-acetylenic tri-n-butylphosphonium salts with the unprecedented C25-3,8-dihydroxy-5,6-epoxyapocarotenal have been completed. Oxidation of the two hydroxyl groups in the left part of the resulting condensation products followed by regioselective oxirane ring opening gave the target carotenoids.
