compounds under mild reaction conditions to afford β,γ-unsaturated α-keto triphenylphorane ylides in good to excellent yields, which were hydrogenated over Pd-C (10%)/H 2 (1 atm) to give the corresponding α-keto triphenylphorane ylides in quasi-quantitative yields. These triphenyphosphorane ylides have been utilized as the precursors to α-keto amide/ester and vicinal tricarbonyl units in Wasserman's synthetic
