Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting enzyme inhibition. Its rigid oxazole-naphthyridine framework enhances binding selectivity, making it valuable in developing kinase inhibitors and antimicrobial agents. The (S)-chirality supports stereoselective interactions in drug-receptor systems, improving efficacy and reducing off-target effects. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its metabolic stability and favorable pharmacokinetic profile.
