Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in complex organic molecules. Its boronate ester group is highly reactive with aryl and vinyl halides in the presence of palladium catalysts, making it valuable in pharmaceutical synthesis and materials science. The dihydropyran ring offers a handle for further functionalization or protection strategies in multistep syntheses. Commonly employed in the preparation of bioactive compounds and conjugated systems for optoelectronic applications.
