Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and natural products. Its protected alcohol and amine functionalities allow selective reactions, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of peptidomimetics and central nervous system agents due to the structural similarity to proline derivatives. The Boc-protected amine enables easy deprotection under mild acidic conditions, facilitating further coupling reactions in solid-phase or solution-phase peptide synthesis.
