concise asymmetricsynthesis of (+)-aphanorphine has been achieved via a new enantioconvergent strategy. A racemic γ-aminoalkene derivative is transformed into a 1:1 mixture of enantiomericallyenriched diastereomers using an asymmetric Pd-catalyzed carboamination. This mixture is then converted to an enantiomericallyenriched protected aphanorphine derivative by a Friedel–Crafts reaction, which generates
