Derivatives of Meldrum's acid and the sodium salts of substituted malonic esters undergo rapid arylation in high yield when treated with aryllead triacetates. These reactions have been applied to the synthesis of ibuprofen, an analgesic, and in a closely related reaction 5-ethylbarbituric acid has been reacted with phenyllead triacetate to give phenobarbital.
当用三乙酸芳基铅处理时,Meldrum酸的衍生物和取代的丙二酸酯的钠盐以高收率进行快速芳基化。这些反应已被用于合成止痛药布洛芬,并且在密切相关的反应中,5-乙基巴比妥酸与三乙酸苯铅反应生成苯巴比妥。
