Used as a key intermediate in the synthesis of complex organic molecules, particularly in pharmaceuticals and natural products. Its structure allows for selective functionalization, making it valuable in constructing polycyclic frameworks. Commonly employed in reactions involving Diels-Alder cycloadditions and photochemical transformations to build fused ring systems. Also utilized in the development of bioactive compounds, including antiviral and anticancer agents, due to its ability to mimic aromatic and heterocyclic motifs found in active drugs.
