Abstract

According to the mechanism involving pallium enolate intermediate in divalent palladium catalyzed nucleophile-alkyne- α,β-unsaturated carbonly tandem additions, the reactions of the enyne ester 1 with electrophiles under the catalysis of divalent palladium were examined. Employing acetyl chloride as the electrophile afforded the β-acetoxyvinyl-γ-butyrolactone 3 as the product, which provided an experimental evidence to the mechanism involving the palladium enolate intermediate.

Key words: PALLADIUM, CATALYSIS, ENOLS, ACETYL CHLORIDE
