Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active compounds. Its rigid cyclohexane backbone and functional groups make it valuable for constructing stereochemically defined molecules. The ethynyl group enables click chemistry reactions, such as the Huisgen cycloaddition with azides, allowing efficient and specific structural elaborations. Commonly employed in medicinal chemistry for creating analogs of bioactive amines, including potential treatments for neurological disorders. Also utilized in the preparation of novel receptor ligands due to its ability to mimic structural motifs found in neurotransmitters.
