Add time:07/17/2019 Source:sciencedirect.com

Treatment of methyl 3-phenylsulphonyl orthopropionate with n-BuLi gives the corresponding carbanion which reacts with aldehydes or ketones to yield β-phenylsulphonyl γ-lactones. Base-catalysed elimination of sulphinic acid yields α,β or β,γ-butenolides.
