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 biaryl and heterobiaryl systems. The tert-butyloxycarbonyl (Boc) protecting group on the azetidine ring allows for selective deprotection and further functionalization, supporting its use in multi-step synthesis of bioactive compounds. Commonly applied in medicinal chemistry for developing drug candidates with azetidine scaffolds, known for improved metabolic stability and favorable physicochemical properties.
