Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and receptor modulators. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to introduce the pyrido[2,3-b][1,4]oxazine scaffold into target molecules. This scaffold is often found in bioactive molecules with potential applications in treating neurological disorders and inflammatory conditions.
