Used as a key intermediate in the synthesis of pharmaceutical peptides and small molecule drugs, particularly in solid-phase peptide synthesis where protection of functional groups is required. Its orthogonal protecting groups (benzyloxycarbonyl and tert-butoxycarbonyl) allow selective deprotection, enabling stepwise assembly of complex molecules. Commonly employed in the preparation of protease inhibitors and other bioactive compounds requiring precise amino group manipulation. Also utilized in medicinal chemistry research for building constrained peptidomimetics due to the piperidine scaffold’s conformational rigidity.
