Used in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. The boronate ester group allows for efficient coupling with aryl or heteroaryl halides, making it valuable in the development of pharmaceuticals and agrochemicals. The protected azetidine ring provides structural stability and can be deprotected to yield active amine-containing compounds. Commonly employed in medicinal chemistry for constructing nitrogen-rich heterocyclic systems with potential biological activity.
