Abstract

Carpanone has been stereoselectively synthesized in 55% yield and six steps from sesamol. The key step of the synthetic sequence is the direct introduction of the propenyl side chain via a Suzuki-Miyaura cross-coupling reaction. The subsequent Pd(II)-catalyzed oxidative coupling yields carpanone as a single diastereoisomer independently of the geometric configuration of the starting precursor. A new mechanism is proposed for this transformation.
