The power of palladium: The totalsynthesis of the alkaloid hodgkinsine B hasbeen achieved with just six isolated intermediates and only four chromatographic operations. The route involves a palladium‐catalyzed enantioselective desymmetrizing N‐allylation of meso‐ chimonanthine to establish the absolute configuration and elaboration of the desymmetrized core by a diastereoselective palladium‐catalyzed
