A facile and efficient method has been developed for the construction of multisubstituted α,β-enones through the direct selective iodosulfonylation of alkylynones with sulfonylhydrazides and iodine pentoxide. The present methodology offers a simple and attractive approach to various multisubstituted α,β-enones in moderate to good yields with excellent stereo- and regioselectivities under the metal- and peroxide-free conditions.
