Used as a key intermediate in organic synthesis, particularly in the preparation of pyrrolidine and pyrroline derivatives, which are important structural motifs in pharmaceuticals and natural products. Its reactivity allows for facile functionalization at multiple sites, making it valuable in constructing complex nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for developing bioactive molecules, including enzyme inhibitors and neuroactive agents. Also utilized in the synthesis of peptidomimetics due to its ability to mimic peptide bonds and stabilize specific conformations.
