Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and kinase inhibitors. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in medicinal chemistry for constructing biaryl systems. Commonly employed in the preparation of drug candidates targeting cancer, inflammation, and viral infections. The cyclopropylamino moiety enhances metabolic stability and binding affinity in final drug molecules. Also utilized in the design of covalent inhibitors due to the reactivity of the boronic acid group with serine residues in enzymes.
