Used primarily in cross-coupling reactions, especially Suzuki-Miyaura coupling, to construct biaryl and heteroaryl frameworks in pharmaceutical and agrochemical synthesis. Its boronate ester group enables efficient and selective bond formation under mild conditions. Commonly employed in the development of organic electronic materials, such as OLEDs and fluorescent dyes, due to the benzo[d]oxazole moiety’s photophysical properties. Also serves as a building block in medicinal chemistry for introducing oxazole-containing fragments into target molecules.
