Used as an intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of protease inhibitors and other therapeutic agents. Its aldehyde functional group allows for further derivatization through reactions such as reductive amination or Wittig transformations, enabling the construction of complex molecules. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine during multi-step syntheses and can be easily removed under mild acidic conditions, making this compound valuable in solid-phase and combinatorial chemistry. Commonly employed in the preparation of peptidomimetics and targeted drug delivery systems.
