Reaktionsschritte
To a solution of benzofuran-3-one (1.00 g, 7.45 mmol) in toluene (25 mL) was added (carboxymethylene)triphenyl phosphorane (3.92 g, 11.2 mmol), and the mixture was refluxed for 24 h. The reaction mixture was cooled to room temperature and concentrated. The residue was purified by column chromatography (hexane, then ethyl acetate:hexane; 1:3) to give a product (0.89 g, 58%). The spectral data for this compound are identical to that reported in the literature. (Deshpande, A. R.; Paradkar, M. V. Syn.Commun., 1990, 20, 809).
