Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct complex indole derivatives with protected functional groups. The Boc group ensures nitrogen protection during reaction steps, while the boronic acid moiety enables carbon-carbon bond formation under mild conditions. Commonly applied in pharmaceutical research for developing serotonin receptor ligands and other bioactive molecules. The methoxy group enhances solubility and can direct regioselective substitution. Stable under various reaction conditions, making it suitable for multi-step synthesis of indole-based drug candidates.
