The oxazolidones and isoxazolidones are a set of six isomeric five-membered heterocyclic compounds consisting of a carbonyl group, an oxygen atom, a nitrogen atom with a hydrogen atom attached, and two methylene groups. The chemicals differ in the relative position of these groups around the ring, which results in different functional group combinations.
