Synthesis of Some Novel Δα,β-Butenolides

Abstract

β-benzoylacrylic acid, a γ-keto acid, has been condensed with various phenolic compounds using concentrated sulphuric acid as condensing agent. The condensation products are ⊿^α,β- butenolides in which γ-carbon atom is attached to two different phenyl rings. Their structures have been established by elemental analysis, chemical reactions and spectral studies.
