Resumen:
e here report the synthesis of 10-aryl-9-hydroxy- and 10-
aryl-9-aminophenanthrenes by reaction of the anions of
9-phenanthrol and 9-aminophenanthrene, respectively, with
aryl halides (iodobenzene, 4-iodoanisole, 9-bromophenantrene).
Good yields of 9,10-disubstituted phenanthrenes were
obtained in these reactions (>75% and 50% for the 9-amino
and 9-hydroxyphenanthrene rings, respectively). Extension
of the procedure to the reaction of both anions with odihalobenzenes
leads to the synthesis of the ring closure
products (aza- or oxa-indeno[1,2-l]phenanthrene), which bear
a pentacyclic aromatic condensed ring system, although in
lower overall yields (35%).
