摘要：

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.
