Used in pharmaceutical synthesis as a chiral building block for active pharmaceutical ingredients (APIs), particularly in the development of neuroactive and antiviral drugs. Its structure supports the formation of bioactive molecules due to the presence of a secondary amine and an amide functional group in a constrained ring system. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting central nervous system disorders. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its favorable conformational and hydrogen-bonding properties.
