Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its rigid piperidine scaffold makes it valuable in medicinal chemistry for modulating the conformation of target compounds, enhancing selectivity and metabolic stability. Commonly employed in the preparation of enzyme inhibitors and receptor ligands, especially in central nervous system (CNS) agents. Also utilized in asymmetric synthesis and catalysis due to its stereogenic center.
