Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring stereochemical control. Its amine and ester functionalities allow for further chemical modifications, making it valuable in medicinal chemistry for constructing cyclic frameworks found in central nervous system agents and enzyme inhibitors. The cis configuration enhances selectivity in drug design, improving potency and reducing off-target effects. Commonly employed in research settings for asymmetric synthesis and optimization of therapeutic candidates.
