The power of palladium : The total synthesis of the alkaloid hodgkinsine B has been 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 α‐oxindole arylation.
