Used as a key intermediate in the synthesis of indole-based pharmaceuticals, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks. Its boronic acid group enables efficient carbon-carbon bond formation, making it valuable in drug discovery for developing bioactive molecules, including kinase inhibitors and serotonin receptor modulators. The Boc-protecting group ensures stability and selective reactivity during multi-step syntheses. Commonly applied in research settings for generating compound libraries in medicinal chemistry.
