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 C 1′ C γ bond).
