Structure-Based Nomenclature for Cyclic Macromolecules
A structure-based nomenclature system for monocyclic and
polycyclic macromolecules is presented. Single-strand mono- and polycyclic
macromolecules as well as spiro macrocyclic compounds are covered. However,
rotaxanes and catenanes, which contain interlocked rings, and rings
or ring systems formed by non-covalent bonds are excluded. The nomenclature
of cyclic macromolecules is based on the existing nomenclature of regular
and irregular polymers, which in turn is based on the nomenclature of
organic chemistry also published by IUPAC. The procedure for naming
a cyclic macromolecule consists of transforming it to an open chain
molecule in such a way that naming of units proceeds in descending order
of seniority. For polycyclic macromolecules main ring, bridges and branch
units are identified and locants for branch units as well as bridges
are assigned before naming according to the rules of this document.
Wherever possible, examples for illustration of the naming procedure
have been chosen from the literature.
