The facile alkylative intra­molecular cyclization of 3-alkoxy­carbonyl-2-oxo­propyl­diphenyl­sulfonium salts is described. This simple method can be readily applied to the synthesis of a novel family of 4-alkylated 3­(2H)-furanones in moderate to high yields under mild conditions via a one-pot process.
