Used as a chiral building block in the synthesis of complex bioactive molecules, particularly in the development of protease inhibitors. Its stereochemistry and functional groups make it valuable in asymmetric synthesis for pharmaceuticals, where precise spatial arrangement is critical for biological activity. Commonly employed in peptide mimetics and enzyme inhibitor design due to its ability to stabilize specific conformations. The Cbz-protected amine and ester groups allow for selective deprotection and further derivatization in multi-step organic syntheses.

Additionally, the dibenzoate esters at positions 3 and 4, along with the 2,2,2-trichloro-1-iminoethoxy group, provide stability to the intermediate and enable easy isolation of products during purification steps. This makes it particularly useful in pharmaceutical and molecular biology research for the efficient synthesis of compounds featuring multiple asymmetric centers.
