Used as a key chiral intermediate in the synthesis of complex natural products and bioactive molecules, particularly in the development of prostaglandin analogs. Its stereochemistry and protected hydroxyl group make it valuable in asymmetric synthesis, enabling selective formation of cyclic structures with high enantiomeric purity. Commonly employed in pharmaceutical research for constructing core frameworks of potent therapeutic agents, especially those targeting inflammation, ocular diseases, and cardiovascular conditions. The triphenylsilyl group acts as a protecting group, allowing selective deprotection and further functionalization in multistep synthetic routes.
