Used as a key intermediate in the synthesis of indole-based pharmaceuticals, particularly in the development of kinase inhibitors and anti-cancer agents. The Boc-protected 2-aminoindole structure allows selective modification at the indole NH or other reactive sites during multi-step syntheses. Commonly employed in medicinal chemistry for constructing substituted indoles, including tryptamine and tryptophan analogs. Also utilized in the preparation of bioactive molecules targeting neurological disorders due to the indole core’s prevalence in serotonin and melatonin derivatives.
