Abstract

This communication describes the synthesis of the fully functionalized C1 to C13 segment (southern part) of highly potent cytotoxic marine natural product mandelalide A. Pd-catalyzed oxa-­Michael cyclization followed by stereoselective reduction of the C7-ketone were carried out to construct the tetrahydropyran unit with required stereochemistry. The α,β-unsaturated ester moiety was constructed via cross-metathesis and the vinyl iodide was installed through modified Takai olefination.
