Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its chiral piperidinone structure makes it valuable for constructing complex nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the ease of functionalization at the carbonyl and amine sites. Also utilized in the preparation of protease inhibitors and central nervous system (CNS) active agents.
