Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring stereochemical control. Its protected amine and ketone functionalities allow for selective transformations, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of cyclic amines and alkaloids, it supports the construction of complex ring systems found in medicinal agents. The Boc-protected amine ensures stability during reactions while enabling deprotection under mild acidic conditions when needed.
