Novel strategy for the synthesis of the butenolide moiety of peridinin

Tartaric acid is the starting point for the stereoselective synthesis of the butenolide unit (see scheme)in peridinin, a marine carotenoid. Key steps were the desymmetrization of tartaric acid bis(Weinreb amide), an E-selective olefination by Ando-type bromophosphonates, and an anti-selective Mitsunobu elimination (for establishing the C1′=Cγ bond).
