A practical and efficient synthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobic oxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach.
描述了一种实用而有效的合成各种1,2,5-三羰基化合物的方法。合成是通过将氰基乙酸甲酯共轭加到α,β-不饱和羰基化合物的β-位上进行的,然后进行碘化铜(I)催化的需氧氧化。另外,已经使用类似的方法合成了各种α-芳基-和α-烷基-α-酮酯。
