2-(5-Resorcinyl)benzofurans have been synthesised by the palladium catalysed cross coupling of 2-trimethylstannyl-or 2-bromozinc benzofurans with the appropriately functionalised 5-iodoresorcinols. These were synthesised by the tri-isopropylsilyloxy directed remote (C-5) lithiation/iodination of the O,O-di(tri-isopropylsilyl)resorcinoltricarbonylchromium(0) complex. The method was applied to the synthesis
