Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. The iodine substituent allows for further functionalization via cross-coupling reactions such as Suzuki or Heck couplings, enabling the construction of complex organic structures. The tert-butyl carbamate (Boc) protecting group stabilizes the pyrrolidine nitrogen during multi-step syntheses and can be easily removed under mild acidic conditions when needed. Commonly employed in the preparation of nitrogen-containing heterocycles and peptidomimetics, especially in research targeting central nervous system agents and enzyme inhibitors.
