Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for introducing the azetidine ring into complex molecules. The boronate ester group enables efficient carbon-carbon bond formation under palladium catalysis, making it valuable in pharmaceutical development where azetidine motifs are present in bioactive compounds. Its protected amine group allows for further functionalization after coupling, offering flexibility in multi-step syntheses. Commonly employed in drug discovery for constructing nitrogen-containing heterocycles with improved metabolic stability and solubility profiles.
