[GRAPHICS]The title compound, a potent protein phosphatase inhibitor and anticancer agent, was prepared by an efficient, multiconvergent asymmetric synthesis. Key transformations include a ring forming olefin metathesis leading to the a-p-unsaturated lactone and creation of the triene moiety via Suzuki cross-coupling.
