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.
