Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders. Its protected hydroxypiperidine structure allows for selective modifications in drug design, making it valuable in creating potent and selective receptor modulators. Commonly employed in medicinal chemistry for constructing complex molecules with improved metabolic stability and bioavailability. Also utilized in the preparation of protease inhibitors and kinase inhibitors due to its favorable stereochemistry and functional group compatibility.
