This compound is primarily utilized in the synthesis of peptides and peptidomimetics, serving as a key building block in the development of pharmaceutical agents. Its structure, featuring both a protected amine group (tert-butoxycarbonyl) and a carboxylic acid, makes it valuable in solid-phase peptide synthesis (SPPS). It is often employed to introduce specific chiral centers into peptide chains, enhancing the biological activity and stability of the final product. Additionally, it is used in the preparation of proline analogs, which are crucial in drug discovery for targeting enzymes and receptors involved in various diseases. Its role in creating constrained peptides also aids in improving pharmacokinetic properties, such as bioavailability and metabolic stability.
