Used as a chiral organoboron reagent in asymmetric synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct enantioenriched biaryl and heterobiaryl compounds. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, while the chiral methoxyethyl side chain directs stereoselectivity in the final product. Commonly employed in the synthesis of pharmaceutical intermediates and bioactive molecules where control of stereochemistry is critical. Stable, easy to handle, and compatible with a wide range of functional groups, making it valuable in medicinal chemistry and process development.
