α,β-Unsaturated sulfones derivatives 5 was prepared from sodium p-toluenesulfinate (1) and the products reacted with substituted-carbomethoxymethyltriphenylarsonium bromide 6 in the presence of potassium carbonate at room temperature to give cyclopropane derivatives 2-substituted-3-substitutedphenyl-4-p-toluenesulfonyl-5-phenyl-trans-2, 3-dihydrofurans 7 and/or 8 with high stereoselectivity.
