2-Phenylbenzofuran (2-phenyl-benzo[b]furan) is a chemical compound that has the molecular formula C₁₄H₁₀O. It is a substituted benzofuran, with a phenyl group as the substituent.

Occurrence and synthesis

2-Phenylbenzofuran is a natural product, and its derivatives (known as 2-phenylbenzofurans) have been isolated from various plants, such as Artocarpus pithecogallus,^[2] legumes, and mulberries.^[3]^[4]

Because there is a substituent at position 2, this benzofuran compound cannot be synthesized by the Perkin rearrangement from a coumarin. However, an alternate sequence has been demonstrated: treatment of 3-phenylcoumarin with aluminium hydride followed by DDQ:^[3]

Applications

2-Phenylbenzofuran and its derivatives have been the subject of research on antioxidant drugs,^[5]^[2] butyrylcholinesterase inhibition,^[6] and leishmaniasis treatment.^[7]
