Routes were investigated for the synthesis of cicerfuran, a hydroxylated benzofuran from wild chickpea implicated in resistance to Fusarium wilt, and some of its analogues. A novel method is described for the synthesis of oxygenated benzofurans by epoxidation and cyclisation of 2′-hydroxystilbenes. The stilbene intermediates required could be synthesised by palladium-catalysed coupling of styrenes

A newroute to the synthesis of 2-arylbenzo[b]furans has been developed. It involves homo/cross-McMurry coupling of salicylaldehyde/substituted salicylaldehydes/aromatic aldehydes to 2-styrylphenols, which undergo intramolecular cyclization with CuBr2 in tetrahydrofuran at ambient temperature to afford 2-arylbenzo[b]furans in good yields.
