ChemInform Abstract: Multisubstituted α,β-Unsaturated γ-Lactones from 1-Chlorovinyl p-Tolyl Sulfoxides and tert-Butyl Carboxylates Using Pummerer-Type Cyclization as the Key Reaction

A procedure for the synthesis of differently substituted γ‐butenolides is developed utilizing Pummerer‐type cyclization of 4‐chloro‐4‐(p‐tolylsulfinyl)butyric acid esters, which are prepared from aldehyde derived 1‐chlorovinyl p‐tolyl sulfoxides, as the key reaction.
