Pj. Campos et al., A SIMPLE SYNTHESIS OF AMINOAZAPOLYCYCLIC COMPOUNDS VIA A PHOTOCHEMICALLY INDUCED CYCLIZATION REACTION OF 3-AMINO-2-ALKENE IMINES IN AN ACID-MEDIUM, Tetrahedron, 54(46), 1998, pp. 14113-14122
We describe the synthesis of benzo-, dibenzo- and naphthoquinolines su
bstituted by alkyl-, arylamino or a NH2 group from irradiation of 3-na
phthyl- and 3-phenanthryl-2-alkene imines under mild reaction conditio
ns. This reaction is suitable for the preparation of four-ring aminoaz
apolycyclic compounds containing a nonaromatic ring. The compounds obt
ained can potentially be used in medicinal chemistry. (C) 1998 Elsevie
