Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with central nervous system activity. Its rigid, fused bicyclic structure makes it valuable in medicinal chemistry for mimicking peptide bonds or serving as a scaffold to enhance metabolic stability and binding selectivity. Commonly employed in the design of enzyme inhibitors and receptor modulators due to its favorable stereochemistry and ability to influence pharmacokinetic properties. Also explored in agrochemical research for creating structurally novel active ingredients.
