Fd. Lewis et al., HETEROCYCLES PHOTOSENSITIZED SYNTHESIS OF PHENANTHRENE FROM 1- AND 9-(AMINOALKYL)PHENANTHRENES, Tetrahedron letters, 35(4), 1994, pp. 535-538
The photosensitized electron transfer reactions of several 1- and 9-(a
minoalkyl)phenanthrenes with metadicyanobenzene have been investigated
. These reactions provide an efficient method of synthesis for the ske
letal structures of the aporphine, phenanthropiperidine, and phenanthr
oazepine alkaloids.
