Radical Cyclization

A novel visible light mediated cyclization of enol lactones with difluoroacyl arenes via a free radical tandem difluoroalkylation and C–C coupling of butenolides is presented. This strategy provides a facile approach to potential biological fluorinated γ-butyrolactones with excellent diastereoselectivity.

AbstractA photocatalyzed and highly efficient trifluoromethylation of N-arylvinylsulfonamides using commercially available CF3SO2Cl as the trifluoromethyl radical source under blue LEDs is reported. The reaction proceeds through radical cyclization under mild conditions. An investigation of the substrate scope is performed to establish a general, synthetically useful protocol for the synthesis of novel trifluoromethylated 1,3-dihydrobenzo[c]isothiazole 2,2-dioxides in moderate to high yields. This method is also successfully applied for the synthesis of difluoromethylated and trifluoroethylated 1,3-dihydrobenzo[c]isothiazole 2,2-dioxides in good to excellent yields.
