Oxygen Heterocycles
Oxygen Heterocycles
Oxygen heterocyclic compounds are organic cyclic compounds containing one or more oxygen atoms in the ring. They may be aliphatic or aromatic in nature. Oxygen heterocycles constitute an important class of heterocyclic compounds largely due to their natural abundance and diverse biological functions. The heterocyclic ring may contain one or more oxygen atoms which influence the physio-chemical and biological properties of the compounds. They can be classified as monocyclic oxygen heterocycles and fused oxygen heterocycles. Some of the monocyclic compounds are oxirane, oxetane, dioxetane, furan, oxolane, dioxolane, dioxane, and trioxane. For fused heterocycles, the examples include benzofuran, dibenzofuran, benzopyran, benzodioxine, chromene, and xanthene.
