Widely used in cross-coupling reactions, especially in Suzuki-Miyaura coupling, this compound serves as a key intermediate in the synthesis of complex organic molecules, including pharmaceuticals and biologically active compounds. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development. The protected dihydroisoquinoline scaffold allows for selective functionalization, which is particularly useful in constructing nitrogen-containing heterocycles found in many therapeutic agents. It is commonly employed in medicinal chemistry for building blocks and library synthesis in high-throughput screening programs.
