SYNTHESIS OF α,β-UNSATURATED SULPHONATES VIA THE WITTIG-HORNER REACTION

Article abstract of DOI:10.1016/S0040-4020(01)87688-2

A general and practical method of synthesis of α,β-unsaturated sulphonates (25 examples) by the Wittig-Horner reaction is described.Reactions with the salts 2 and carbonyl compounds are not very stereoselective.On the contrary, reactions with esters 1 gave high yields of (E)-α,β-unsaturated sulphonic esters.
