Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates targeting central nervous system disorders. Its structure allows for selective functionalization, making it valuable in creating peptidomimetics and conformationally restricted analogs. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles, it supports the optimization of pharmacokinetic properties such as metabolic stability and bioavailability. Also utilized in solid-phase and solution-phase peptide synthesis where controlled stereochemistry is required.
