Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role. Its protected amine functionality and rigid cyclohexane backbone make it valuable in asymmetric synthesis and catalysis. Commonly employed in the preparation of protease inhibitors and other bioactive molecules requiring defined spatial orientation. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational restraint.
