Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antidiabetic agents. Its rigid bicyclic structure enhances metabolic stability and bioavailability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic peptide bonds and influence conformational restriction. Also utilized in the preparation of enzyme inhibitors where stereochemistry and ring strain play critical roles in binding affinity.
