A synthetic approach to the heterodimeric bisindole alkaloid leucophyllidine is disclosed herein. An enantioenriched lactam building block, synthesized through palladium-catalyzed asymmetric allylic alkylation, served as the precursor to both hemispheres. The eburnamonine-derived fragment was synthesized through a Bischler–Napieralski/hydrogenation approach, while the eucophylline-derived fragment was synthesized by Friedl?nder quinoline synthesis and two sequential C?H functionalization steps. A convergent Stille coupling and phenol-directed hydrogenation united the two monomeric fragments to afford 16′-epi-leucophyllidine in 21 steps from commercial material.
