Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure allows for selective modification in multi-step organic reactions, making it valuable in medicinal chemistry for building complex drug candidates. Commonly employed in research settings for constructing peptidomimetics due to the presence of protected amine and ester functionalities, which enable controlled coupling and deprotection steps. Also utilized in the preparation of enzyme inhibitors where naphthyl group imparts favorable binding interactions.
