Used primarily in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. It enables the formation of carbon-carbon bonds, particularly in the construction of biaryl or heterobiaryl systems found in pharmaceuticals and agrochemicals. The compound’s dihydroquinolinone core provides a scaffold useful in drug discovery, while the boronate group allows for efficient and selective coupling under mild palladium catalysis. It is especially valuable in the development of bioactive molecules and functional materials requiring precise molecular architecture.
