Treatment of conjugated enones having both α'- and γ-hydrogens with KN(SiMe3)2 (KHMSA) in a mixed solvent of DMF with THF at -78 deg C afforded preferentially linear-conjugated dienolate anions, which were trapped by methyl chloroformate to give the corre

The reactions of the ketones 2,2-bromoketones 6, α,β-unsaturated ketones 8, 1,2-diketones, and aliphatic aldehydes 20 with trialkylsilyl triflates 1 in the presence of triethylamine (4) at room temperature yield the silyl enol ethers 3, 7, 9, 11, and 21.The silylation of the unsymmetrical ketones 12 with 1a/4 runs regioselectively in the thermodynamical sense using 1a/12 in excess and yields the enol ethers 13t.The course of this reaction is discussed briefly.
