beta-Keto esters and beta-keto amides can be efficiently alkylated on reaction with enol ethers and manganese(III) acetate in the presence of copper(II) acetate. These intermolecular radical addition reactions can be used to construct quaternary carbon centres in excellent yield and this method has been utilised in a diastereoselective approach to substituted pyrrolidinones.
在乙酸铜(II)的存在下,与烯醇醚和乙酸锰(III)反应,可以有效地将β-酮酯和β-酮酰胺烷基化。这些分子间自由基加成反应可用于以优异的产率构建季碳中心,并且该方法已经以非对映选择性的方式用于取代的吡咯烷酮。
