Used in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active indole derivatives. It serves as a key intermediate in pharmaceutical research, particularly in the development of drug candidates targeting inflammation, cancer, and central nervous system disorders. The boronic acid group enables efficient carbon-carbon bond formation with aryl halides, while the Boc-protected indole ensures stability and selectivity during reactions. Commonly employed in medicinal chemistry for building complex heterocyclic structures found in drug molecules.
