aporphines by reaction with benzodioxole, pyridine N-oxide and pyrazine N-oxide. Successful application of direct arylation in these diversification reactions highlights its utility not only in convergent, but also in divergent synthesis. We also describe enantioselective syntheses of (R)-nornuciferine and (R)-nuciferine employing a catalytic asymmetrictransferhydrogenation in high yield and excellent enantiomeric
