13oxazolone

13oxazolone, sometimes written 13-oxazolone, is a designation that appears in a limited subset of chemical literature to refer to an oxazolone-containing compound labeled as “13” within a study or dataset. There is no universally defined structure associated with the label; different sources may use it to denote different derivatives of the oxazolone core, or a specific oxazolone unit within a larger molecule. As a result, structural and spectral data for 13oxazolone are not consolidated in standard chemical catalogs, and the exact identity can vary by source.

Chemical context: Oxazolones are heterocyclic lactam-lactones derived from a 1,3-oxazolone ring. The core features a five-member ring containing nitrogen and oxygen with a carbonyl group. Substitution at various positions on the ring or on adjacent moieties gives rise to numerous derivatives. In general, oxazolone motifs are used as reactive building blocks in organic synthesis, capable of participating in cycloadditions and nucleophilic openings, which enables diverse routes to natural products, pharmaceuticals, and other functionalized scaffolds. Specific data for 13oxazolone, including exact substituents, synthesis, and spectral properties, depend on the published source.
