In this study, the (S)-enantiomers of the aporphine alkaloids, nuciferine and roemerine, were prepared via a synthetic route involving catalytic asymmetric hydrogenation and both stereoisomers were evaluated in vitro for functional activity at human 5-HT2 and adrenergic α1 receptor subtypes using a transforming growth factor-α shedding assay. Both enantiomers of each of the compounds were found to act as antagonists at 5-HT2 and α1 receptors. (R)-roemerine was the most potent compound at 5-HT2A and 5-HT2C receptors (pKb = 7.8-7.9) with good selectivity compared to (S)-roemerine at these two receptors and compared to its activity at 5-HT2B, α1A, α1B and α1D receptors.

Palladium-catalyzed direct arylation of aryl chlorides, bromides and iodides has been applied to the preparation of new aporphine analogues including C2-substituted 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 asymmetric transfer hydrogenation in high yield and excellent enantiomeric excess.

Bischler-Napieralski cyclisation of N--2'-bromophenylacetamide (3) followed by manganese dioxide oxidation of the crude amine (4) gives 1-(2'-bromobenzoyl)-3,4-dihydro-6,7-methylenedioxyisoquinoline (5) which is aromatis
