Used primarily in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. Its boronate ester group facilitates coupling with aryl or vinyl halides under palladium catalysis, making it valuable in the preparation of complex organic molecules, particularly in pharmaceutical and agrochemical research. The tetrahydroisoquinoline moiety provides a rigid, nitrogen-containing scaffold often found in biologically active compounds, enhancing its utility in drug discovery and development of therapeutic agents targeting central nervous system disorders and other diseases.
