STEROIDS (seco-steroids C07C) [2018-08]
NOTE

  • This subclass covers compounds containing a cyclopenta[a]hydrophenanthrene skeleton or a ring structure derived therefrom:
    • by contraction or expansion of one ring by one or two atoms;
    • by contraction or expansion of two rings each by one atom;
    • by contraction of one ring by one atom and expansion of one ring by one atom;
    • by substitution of one or two carbon atoms of the cyclopenta[a]hydrophenanthrene skeleton, which are not shared by rings, by hetero atoms, in combination with the above defined contraction or expansion or not, or;
    • by condensation with carbocyclic or heterocyclic rings in combination with one or more of the foregoing alterations or not.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
