1,3-Dicarbonyl compounds including ethyl 2-methylacetoacetate can be efficiently alkylated with enol ethers or enolesters in the presence of manganese(III) acetate. These intermolecular radical addition reactions can be used to form sterically congested quaternary carbon centres in excellent yield (81-97%).
