Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and anti-inflammatory agents. The tert-butyl carbamate group serves as a protecting group for amines, enabling selective reactions in multi-step organic syntheses. Its isoxazole ring contributes to enhanced metabolic stability and binding affinity in bioactive molecules. Commonly employed in medicinal chemistry for constructing drug candidates targeting cancer, autoimmune diseases, and central nervous system disorders.
