Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex indole derivatives, which are key scaffolds in pharmaceuticals and agrochemicals. The boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development of bioactive molecules. Its sulfonyl group enhances stability and influences electronic properties, improving reaction selectivity. Commonly applied in the preparation of potential therapeutic agents, including kinase inhibitors and anti-inflammatory compounds.
