Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronate ester group facilitates carbon-carbon bond formation under mild conditions, making it valuable for constructing drug-like scaffolds. The tert-butyloxycarbonyl (Boc) protecting group ensures stability and controlled deprotection during multi-step syntheses. Commonly applied in the development of bioactive compounds where azetidine rings serve as rigid structural motifs to enhance metabolic stability and binding affinity.
