Used primarily as an intermediate in pharmaceutical synthesis, especially in Suzuki-Miyaura cross-coupling reactions to construct biaryl or aryl-heteroaryl frameworks. The boronate ester group enables efficient carbon-carbon bond formation under palladium catalysis, making it valuable for building complex organic molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs) where cyclobutyl and aryl motifs are part of the target structure. The tert-butyl carbamate (Boc) group protects the amine during synthesis and can be removed selectively under acidic conditions, allowing for further functionalization downstream. Its stability and reactivity profile make it suitable for use in multi-step synthetic routes in medicinal chemistry.
