Abstract

AbstractA highly efficient and eco-friendly method has been developed for the synthesis of allyl sulfones using Morita–Baylis–Hillman (MBH) adducts and thiosulfonates under mild conditions. The Cs2CO3-promoted radical sulfonylation provided a series of allyl sulfones in good to high yields with high stereoselectivities. A wide variety of MBH bromides/acetates as well as thiosulfonates were tolerated and reliable in scaled-up synthesis. A plausible mechanism is proposed to rationalize the radical sulfonylation.
