Abstract
AbstractAn additive‐ and external oxidant‐free reaction of cyclopropanols, DABCO ⋅ (SO2)2 and diaryliodonium salts in aqueous phase is described. This reaction proceeds under mild reaction conditions, affording bioactive aryl substituted γ‐keto sulfones in 36%‐90% yields with good functional group tolerance. This reaction proceeds through a γ‐keto sulfinate intermediate, which undergoes a nucleophilic reaction with diaryliodonium salts, giving rise to corresponding aryl substituted γ‐keto sulfones.
