Thiophene, pyrrole and Furan are all five membered heterocyclic aromatic compounds, with the hetero atom being sulfur (S), nitrogen (N) and oxygen (O) respectively. Epoxides are easily prepared by reaction of alkenes with peracids, usually with good stereospecificity. For example, nucleic acids, the chemical substances that carry the genetic information controlling inheritance, consist of long chains of heterocyclic units held together by other types of materials.Many naturally occurring pigments, vitamins, and antibiotics are heterocyclic compounds, as are most hallucinogens.
