The heterocyclic compound 2-arylbenzofurans consists of fused benzene and furan rings along with different substituted groups (complex structures) at the C-2 position. These compounds show a wide range of pharmacological properties including anticancer [ 5 ], antibacterial [ 6 ], antimicrobial [ 7 ], antifungal [ 8 ], anticonvulsant [ 9 ], anti. Derivatives such as 3-unsubstituted 2-arylbenzofurans often have biological activities such as anticancer, antimicrobial, and antioxidant properties. However, methods for their synthesis are often complex, involve the use of expensive reagents or catalysts, or have low yields.

Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. Several approaches have been reported for the construction of benzofurans and naphthofurans. Recently, Singh and Writh utilized DIB-promoted metal-free cyclization of o-hydroxystilbenes to prepare 2-arylbenzofurans (Scheme 40).
