Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports the construction of complex organic frameworks with high stereoselectivity. Commonly employed in medicinal chemistry for building chiral pyrrolidine-based scaffolds that enhance metabolic stability and binding affinity in drug candidates. Also utilized in solid-phase and solution-phase peptide synthesis due to the presence of the Boc-protecting group, allowing for controlled amine deprotection and coupling reactions.
