Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of alkaloid-based drugs such as tetrahydroisoquinoline derivatives. Its structure supports the construction of complex nitrogen-containing heterocycles, which are common in bioactive molecules. Frequently employed in medicinal chemistry for creating analogs of natural products with potential neurological or cardiovascular activity. The Boc-protected amine, 6-hydroxy, and carboxylic acid functionalities allow for selective reactions in multi-step syntheses, making it valuable in solid-phase and solution-phase peptide-like assembly processes.
