Used as an intermediate in the synthesis of chiral pharmaceuticals and fine chemicals, particularly in the preparation of optically active esters and amides. Its reactivity allows for selective acylation under mild conditions, making it valuable in asymmetric synthesis. Commonly employed in the development of antibiotics and enzyme inhibitors due to its ability to form stable derivatives with amines and alcohols. Also utilized in peptide mimetic construction where stereochemistry plays a critical role in biological activity.
