Introduction to Heterocycles

Trivial Names of Heterocyclic Compounds

In the case of heterocycles, systematic nomenclature is usually hardly ever applied. Instead, trivial names are frequently used. Aromatic heterocycles are typically only known by their trivial names.

In the naming of heterocycles that have a more complex structure, the trivial names of simple heterocycles are often used as the parent name. In addition, the trivial names of aromatic heterocycles frequently serve as parent names for the naming of the corresponding saturated heterocycles. The cyclic ether oxacyclopentane (oxolane) is usually only known as tetrahydrofuran and oxacyclohexane (oxane) is usually called tetrahydropyrane.
