Id1 R: CI 75 7. atives can be directly effected by several reagents.'However, yields are often moderate and experimental conditions are not always compatible with the presence of sensitive functional groups. The sulfenylation'of enolates of esters, followed by oxidation to the corresponding sulfoxides and thermolysis, offers a wider synthetic applicability and should definitely supersede the more traditional approach involving a bromination- ...
