Used in the synthesis of peptidomimetics and pharmaceutical intermediates, particularly in the development of protease inhibitors. Its aldehyde functional group enables selective reactions such as reductive amination and aldol condensation, making it valuable in constructing chiral building blocks for drug discovery. The Boc-protected amine ensures stability during multi-step syntheses, while the chiral center allows for stereocontrolled transformations. Commonly employed in the preparation of bioactive molecules, including enzyme inhibitors and receptor modulators.
