Used in pharmaceutical synthesis, particularly as a chiral building block for active pharmaceutical ingredients (APIs). Its stereochemistry makes it valuable in the development of drugs targeting central nervous system disorders and metabolic diseases. Commonly employed in the preparation of protease inhibitors and receptor agonists due to its ability to enhance selectivity and binding affinity. Also utilized in the synthesis of novel kinase inhibitors and antidiabetic agents. Its structural rigidity and hydrogen-bonding capability improve pharmacokinetic properties in drug candidates.
