Heterocyclic compounds

Heterocyclic compounds are a class of organic compounds with cyclic structure. The ring-constituting atoms in the molecule, in addition to carbon, also include one or more nitrogen, sulfur, oxygen and other atoms. Those containing one ring are called single-heterocyclic compounds, such as furan, thiazole, and pyridine. Those containing two or more rings are called fused heterocyclic compounds such as quinoline and purine.
