Used in organic synthesis as a protected indole derivative for the construction of complex nitrogen-containing heterocycles. The Boc group stabilizes the nitrogen during reactions, while the iodine at the 3-position allows for further functionalization via cross-coupling reactions such as Suzuki, Stille, or Sonogashira couplings. Commonly employed in pharmaceutical research for developing indole-based bioactive molecules and natural product analogs. Its protected form enables selective reactivity, making it valuable in multi-step synthesis of medicinal compounds.
