Used in pharmaceutical synthesis as a protected amine intermediate, particularly in the development of bioactive molecules targeting central nervous system disorders. Its rigid polycyclic structure makes it valuable for enhancing binding selectivity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical stability and favorable pharmacokinetic properties. Also utilized in the preparation of proline analogs and peptidomimetics for enzyme inhibition research.
