Used as a key intermediate in the synthesis of antiviral and antidiabetic agents, particularly in the development of inhibitors targeting viral proteases or enzymes involved in glucose metabolism. Its rigid, polycyclic structure with defined stereochemistry makes it valuable for designing potent and selective bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates. Also utilized in the preparation of peptidomimetics due to its ability to mimic peptide motifs while enhancing metabolic stability.
