heterocyclic compound - Encyclopedia Britannica
2024年10月18日 · Heterocyclic compound, any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an element other than carbon (C).
Heterocyclic Compounds -Definition, Classification, Examples ...
2023年8月13日 · Heterocyclic compounds are cyclic compounds with at least one atom other than carbon in the ring, like N, P, O, S, and so on. Most heterocyclic compounds contain only nitrogen, oxygen, and sulphur as heteroatoms. Five- or six-membered rings of heterocyclic compounds are the most stable.
Heterocyclic Chemistry - Michigan State University
Heterocyclic rings are found in many naturally occurring compounds. Most notably, they compose the core structures of mono and polysaccharides , and the four DNA bases that establish the genetic code.
Heterocyclic Compound - BYJU'S
What is a Heterocyclic Compound? A heterocyclic compound has at least two different elements as a member of its ring. The most common hetero atoms found on a cyclic ring are Oxygen (O), Nitrogen (N) and Sulphur (S). Example:
Heterocyclic compounds: Nomenclature, Types, Applications
2023年7月25日 · Heterocyclic compounds contain at least one heteroatom (atom other than carbon) in the cyclic ring structure. The three most frequent heteroatoms are nitrogen (N), oxygen (O), and sulfur (S). Heterocyclic compounds are commonly found in plants and animal products, and they are a key element of over half of all known natural organic compounds.
Heterocyclic Compound - an overview | ScienceDirect Topics
The heterocyclic compounds play an important role in regulating the biochemical process in living system. The compounds may be genetic material, hormones, and enzymes. The common heterocyclic compounds that serve as potential leading drug candidates include amino acid, vitamins, and coenzymes.
4.12: Heterocyclic Aromatic Compounds - Chemistry LibreTexts
2020年10月16日 · In heterocyclic aromatic compounds, at least one carbon atom is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. Examples of heterocyclic aromatic compounds are furan , a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine , a heterocyclic compound with a six-membered ring containing ...
Heterocyclic compound - Aromatic, Aliphatic, Heteroatoms
2024年10月18日 · Since 1950, five different classes of three-membered ring compounds with two heteroatoms have been discovered. They are derivatives of the parent ring systems diaziridine (containing N―N), oxaziridine (O―N), thiaziridine (S―N), dioxirane (O―O), and dithiirane (S―S). The oxathiirane system has no reported stable representatives in its class.
15.5: Aromatic Heterocycles - Pyridine and Pyrrole
Cyclic compounds that include one or more elements other than carbon are called a heterocycle. The most common heterocyclic compounds contain carbon along with nitrogen, oxygen, or sulfur. Because some heterocyclic compounds are aromatic, it is important to discuss how the inclusion of non-carbon atoms affects the determination of aromaticity.
