Used in pharmaceutical synthesis as a chiral building block for the development of bioactive molecules. Its protected amine group allows for selective deprotection and coupling in peptide-like structures, making it valuable in the design of protease inhibitors and receptor ligands. Commonly employed in the preparation of drug candidates targeting central nervous system disorders due to the piperidine moiety’s prevalence in neuroactive compounds. The (S)-configuration enables stereocontrolled synthesis, enhancing potency and selectivity in final active ingredients.
