The syntheticmethods of 2,3-disubstituted benzofurans have been widely studied, however, the maneuvers of using o-alkenyl phenols as starting materials are less explored. Herein, we report a general and efficient strategy via HNTf2/TMSOTf catalyzed cascade reaction with readily available o-alkenyl phenols and aldehydes as starting materials, which provides 2,3-disubstituted benzofuran derivatives
