We have established an efficient ruthenium(II) and iodine anion cocatalyzed dihalogenation cascade cyclization of internal alkyne-tethered cyclohexadienones, which stereoselectively afforded numerous products with a bioactive hydrobenzofuran skeleton in high yields under mild conditions. In this transformation, the reaction pathway was determined by concentration electrophilic reagent, also provided strategy for control selectivity. Furthermore, method features use 1,2-dihaloroethane as halogen source via catalyst.
