Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports the formation of complex heterocyclic compounds, making it valuable in medicinal chemistry for drug discovery. Commonly employed in the preparation of analogs for structure-activity relationship (SAR) studies due to its stable ring system and functional group compatibility. Also utilized in the manufacture of kinase inhibitors and central nervous system (CNS) active agents. Suitable for solid-phase and solution-phase peptide-like synthesis owing to its amine and ester functionalities.
