Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group facilitates coupling with aryl or vinyl halides under palladium catalysis, making it valuable in pharmaceutical and agrochemical research for constructing substituted biaryl or cyclopropane-containing structures. The ethyl ester moiety can be further modified, allowing for downstream functionalization in multi-step synthetic routes. Commonly employed in medicinal chemistry for building constrained analogs to explore structure-activity relationships.
