An efficient synthesis of the title compound has been developed from 3- phenyl sulfonylpropanoic acid via the butenolide 2. The key synthetic step is a Diels-Alder reaction. A mechanism is suggested.

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 yields α,β or β,γ-butenolides.
