Used primarily in the synthesis of pharmaceutical intermediates, especially in the development of immunomodulatory drugs. It serves as a chiral building block in the preparation of potent cereblon E3 ligase modulators, which are key in targeted protein degradation therapies. Its protected amine group allows for selective functionalization, making it valuable in solid-phase and solution-phase peptide-like drug synthesis. Commonly employed in research for oncology and inflammatory disease drug discovery due to its structural role in bioactive molecules.
