Used in organic synthesis as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its boronate ester group facilitates efficient coupling with aryl or heteroaryl halides under palladium catalysis, making it valuable in constructing complex molecules for drug discovery. The protected oxazepine scaffold is particularly useful in medicinal chemistry for building bioactive compounds targeting central nervous system disorders and inflammation-related diseases.
