Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its protected amine and defined stereochemistry make it valuable in constructing complex molecules for drug discovery, especially in central nervous system agents and enzyme inhibitors. Commonly employed in peptide mimetics and medicinal chemistry routes where a constrained piperidine scaffold is needed. The benzyl carbamate group allows for easy deprotection under mild conditions, enabling further functionalization in multi-step syntheses.
