Reported herein is an intramolecular dehydrogenative coupling of two inert aryl C-H bonds for the synthesis of aporphine analogues. The process represents a novel tool for the preparation of aporphines via palladiun-catalyzed C-H bond activation. The present reaction is compatible with various functional groups, and the coupling products have been further applied for the synthesis of natural products aporphine and zenkerine.
A convenient formation of aporphine core via benzyne chemistry: Conformational analysis and synthesis of (R)-aporphine

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 enantiomerically enriched aporphine alkaloid.
Synthesis of (±)-aporphine utilizing Pictet-Spengler and intramolecular phenol ortho-arylation reactions
Cuny, Gregory D.
, p. 5167 - 5170 (2007/10/03)
A synthesis of the alkaloid (±)-aporphine is reported. The initial key step of the synthesis involves a Pictet-Spengler cyclization of N-tosyl tyramine with 2-bromophenylacetaldehyde in trifluoroacetic acid. This step was followed by the second strategic
PHOTOSENSITIZED SYNTHESIS OF PHENANTHRENE HETEROCYCLES FROM 1- AND 9-(AMINOALKYL)PHENANTHRENES
Lewis, Frederick D.,Reddy, G. Dasharatha,Cohen, Bliss E.
, p. 535 - 538 (2007/10/02)
The photosensitized electron transfer reactions of several 1- and 9-(aminoalkyl)phenanthrenes with meta-dicyanobenzene have been investigated.These reactions provide an efficient method of synthesis for the skeletal structures of the aporphine, phenanthropiperidine, and phenanthroazepine alkaloids.
