()-Corey lactone diol is widely used as a key intermediate in the synthesis of various biologically active compounds, particularly in the pharmaceutical industry. It serves as a crucial building block for the production of prostaglandins and prostacyclins, which are important for their roles in inflammation, blood clotting, and other physiological processes. Additionally, it is utilized in the preparation of chiral compounds, enabling the development of enantiomerically pure drugs. Its versatility in organic synthesis also extends to the creation of complex natural products and fine chemicals, making it a valuable tool in medicinal chemistry and drug discovery.
