ACYCLIC OR CARBOCYCLIC COMPOUNDS

Notes

(1)

In this subclass, the following terms or expressions are used with the meanings indicated:

–

"bridged" means the presence of at least one fusion other than ortho, peri or spiro;

–

two rings are "condensed" if they share at least one ring member, i.e. "spiro" and "bridged" are considered as condensed;

–

"condensed ring system" is a ring system in which all rings are condensed among themselves;

–

"number of rings" in a condensed ring system equals the number of scissions necessary to convert the ring system into one acyclic chain;

–

"quinones" are compounds derived from compounds containing a six-membered aromatic ring or a system comprising six-membered aromatic rings (which system may be condensed or not condensed) by replacing two or four

CH groups of the six-membered aromatic rings by

C=O groups, and by removing one or two carbon-to-carbon double bonds, respectively, and rearranging the remaining carbon-to-carbon double bonds to give a ring or ring system with alternating double bonds, including the carbon-to-oxygen bonds; this means that acenaphthenequinone or camphorquinone are not considered as quinones. [5]

(2)

Therapeutic activity of compounds is further classified in subclass A61P. [7]

(3)

In this subclass, in the absence of an indication to the contrary, a process is classified in the last appropriate place. [3]

(4)

In this subclass, in the absence of an indication to the contrary, "quaternary ammonium compounds" are classified with the corresponding "non-quaternised nitrogen compounds". [5]

(5)

For the classification of compounds in groups C07C 1/00 to C07C 71/00 and C07C 401/00 to C07C 409/00 :

–

a compound is classified considering the molecule as a whole (rule of the "whole molecule approach");

–

a compound is considered to be saturated if it does not contain carbon atoms bound to each other by multiple bonds;

–

a compound is considered to be unsaturated if it contains carbon atoms bound to each other by multiple bonds, which includes a six-membered aromatic ring,

unless otherwise specified or implicitly derivable from the subdivision, as in group C07C 69/00, e.g. C07C 69/712. [5]

(6)

For the classification of compounds in groups C07C 201/00 to C07C 395/00, i.e. after the functional group has been determined according to the "last place rule", a compound is classified according to the following principles:

–

compounds are classified in accordance with the nature of the carbon atom to which the functional group is attached;

–

a carbon skeleton is a carbon atom, other than a carbon atom of a carboxyl group, or a chain of carbon atoms bound to each other; a carbon skeleton is considered to be terminated by every bond to an element other than carbon or to a carbon atom of a carboxyl group;

–

when the molecule contains several functional groups, only functional groups linked to the same carbon skeleton as the one first determined are considered;

–

a carbon skeleton is considered to be saturated if it does not contain carbon atoms bound to each other by multiple bonds;

–

a carbon skeleton is considered to be unsaturated if it contains carbon atoms bound to each other by multiple bonds, which includes a six-membered aromatic ring. [5]

(7)

In this subclass, it is desirable to add the indexing codes of subclass C07M. The indexing codes should be unlinked. [6]
