  • Title: Synthesis of two bioactive natural products: FR252921 and pseudotrienic acid B.
    Author: Amans D, Bellosta V, Cossy J.
    Journal: Chemistry; 2009; 15(14):3457-73. PubMed ID: 19219867.
    Abstract:
    Concise and highly convergent syntheses of the immunosuppressive agent FR252921 and the related antimicrobial natural product pseudotrienic acid B were achieved from a common intermediate by using optically active titanium complexes to control the configuration of the stereogenic centers, a highly stereo- and regioselective cross-metathesis to generate the triene moieties, and a Stille cross-coupling to install the dienic units.
