Widely used in peptide synthesis, this compound serves as a chiral building block for introducing constrained amino acid residues into peptide chains. Its cyclohexane backbone provides structural rigidity, which helps stabilize specific peptide conformations, making it valuable in the design of bioactive peptides with improved selectivity and metabolic stability. The Fmoc group allows for orthogonal protection in solid-phase peptide synthesis, enabling stepwise assembly under mild basic conditions. It is particularly useful in the development of peptidomimetics and in medicinal chemistry for probing structure-activity relationships in receptor ligands.
