Asymmetric Total Synthesis of (+)-Fostriecin

Abstract

[structure: see text] 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 alpha,beta-unsaturated lactone and creation of the triene moiety via Suzuki cross-coupling.
