Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals. It serves as a building block for creating compounds with biological activity, including potential use in central nervous system agents due to its structural similarity to known neuroactive molecules. Its carbonyl and amide functionalities allow for further chemical modifications, making it valuable in medicinal chemistry research for designing enzyme inhibitors or receptor ligands. Also employed in the synthesis of cyclic peptides and peptidomimetics, where the constrained ring structure contributes to enhanced metabolic stability and selectivity.
