A convenient formation of aporphine core via benzyne chemistry: conformational analysis and synthesis of (R)-aporphine
摘要:
Total synthesis of (R)-aporphine has been accomplished by an approach that employs in the key step a sequence of transformations involving a [4+2] cycloaddition reaction followed by a hydrogen migration, leading to aporphine core in good yield, which was subjected to a 1D gradient NOE experiment, conformational analysis, and simple transformations, including a small scale resolution process, to afford enantiomericallyenriched aporphine alkaloid.

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
