NOTE

  • This subclass covers compounds containing a cyclopenta[a]hydrophenanthrene skeleton or a ring structure derived therefrom:

    • by contraction of one ring by one atom and expansion of one ring by one atom;

    • by condensation with carbocyclic or heterocyclic rings in combination with one or more of the foregoing alterations or not.
