Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key intermediate in the synthesis of pharmaceuticals and biologically active molecules. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. It is particularly useful in the development of CNS-active agents and kinase inhibitors due to the structural similarity of its dihydroisoquinolinone core to natural alkaloids. The compound’s stability and reactivity profile also make it a preferred building block in library synthesis for drug discovery programs.
