Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and bioactive molecules. The Cbz-protected amino group and free carboxylic acid functional groups make it valuable in the construction of peptide-like structures and asymmetric synthesis. Commonly employed in medicinal chemistry for constructing constrained ring systems that enhance metabolic stability and target selectivity. Also utilized in the preparation of intermediates for protease inhibitors and central nervous system agents.
