Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and targeted cancer therapies. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing biaryl frameworks found in bioactive molecules. The Cbz-protected amine allows for selective deprotection and further functionalization in multi-step syntheses. Commonly employed in medicinal chemistry for creating peptide mimetics and enzyme inhibitors, especially in drugs targeting serine proteases.
