Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors. Its rigid, stereochemically defined structure makes it valuable in medicinal chemistry for constructing peptidomimetics—molecules that mimic peptides but with improved metabolic stability and bioavailability. The sulfone group enhances polarity and can participate in hydrogen bonding, aiding in target binding. This compound is especially useful in research settings for optimizing drug candidates targeting viral enzymes and other biological pathways where conformational restraint is beneficial.
