Reaction of triphenylphosphine with unsymmetrical electrophiles such as alkyl propiolates in the presence of 2-acetylbutyrolactone gives alkyl 2-(3-acetyl-2-oxotetrahydro-3-furanyl)acrylate and α-methylene-γ-butyrolactone derivatives.
Keywords: Alkyl propiolate, 2-acetylbutyrolactone, triphenylphosphine, α-methylene-γ-butyrolactone.
