Iejimalides constitute a new family of marine natural products with remarkable and unprecedented biological properties. Furthermore, their unique structural features: 24-membered ring macrolactone, six stereocenters and four dienic systems make it a challenging target for organic chemists. Our efforts towards the total synthesis of Iejimalide B based on alkene metathesis and metal catalyzed Csp2-Csp2 couplings will be presented.
