摘要：

Trimethylsilyl dienol ethers are easily oxidized by ceric ammonium nitrate to give alpha-carbonylallyl radicals which are able to add to enolic carbon-carbon double bonds with very high gamma regioselectivity, allowing the method to be applied to the synthesis of 6-oxo-alpha,beta-unsaturated carbonyl compounds.
