Used in organic synthesis as a key intermediate for constructing complex natural product frameworks, particularly in the preparation of lignan analogs with potential biological activity. Its methoxy and ester functionalities allow for selective transformations, such as demethylation, hydrolysis, and coupling reactions, enabling the development of pharmaceuticals and bioactive molecules. Commonly employed in research targeting anticancer, antioxidant, and anti-inflammatory compounds due to the structural similarity to naturally occurring dibenzylbutyrolactone lignans. Also utilized in material science for designing chiral ligands and functionalized aromatic systems.
