A highly practical route to oligostilbenoid natural products is described. A regioselective Bi(OTf)3-catalyzed cyclodehydration provided ready access to 3-arylbenzofuran. Pd-catalyzeddirectC–Hactivation of benzofuran and subsequent cross-coupling with aryl halide was successfully implemented for the introduction of aryl group at the C2 position of benzofuran. Further manipulation of the 2,3-diarylbenzofuran
