Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) involving pyrrolidine-based structures. Its functional group allows for alkylation and cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the production of neuroactive compounds and receptor ligands due to the pyrrolidine ring’s presence in bioactive molecules. Also utilized in the preparation of chiral auxiliaries and catalysts for asymmetric synthesis.
