Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex indole derivatives. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in pharmaceutical research and development of bioactive molecules. Commonly applied in the preparation of drug candidates targeting neurological disorders, inflammation, and cancer due to the indole scaffold’s prevalence in medicinal chemistry. Stable and compatible with a wide range of functional groups, it supports late-stage functionalization in organic synthesis.
