Introduction a-Trimethylsilyl ketones are versatile synthetic reagents for organic syntheses. l However, they are relatively inaccessible because trimethylsilylation of the corresponding ketones gives only the silyl enol ethers? Roundabout ways have been employed for their~ yntheses.~ Larson reported that methyldiphenylsilylation of esters favors the formation of the C-silylated product: but this procedure was unsuccessful in attempts to produce the a- ...
