The invention discloses a synthetic method of oxidized nantenine and application of the oxidized nantenine. The synthetic method of the oxidized nantenine comprises the following steps: taking 2-(benzo[d][1,3]dioxol-5-yl)acetic acid and 3,4-dimethoxy phenethylamine as starting materials, and conducting seven-step reaction to synthesize the oxidized nantenine. Compared with the prior art, the organic complete synthetic method of the oxidized nantenine is provided by the invention; experiments indicate that the oxidized nantenine has a proliferation inhibitory activity against a plurality of human tumor cell strains, shows up a good antitumor activity in vitro, is excellent in potential medicinal value, and can be applied to preparation of various anti-tumor drugs.

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.
