Disubstituted malonic acid derivatives are smoothly converted into diketones and ketoesters in good to excellent yield (68% to 91%) under electrochemical conditions. The scope can be extended to transform trisubstituted bis-malonic acids into tetraketones in 77% to 86% yield. The new method was applied to the total synthesis of cis-jasmone.
在电化学条件下,二取代的丙二酸衍生物可以良好至极佳的收率(68%至91%)顺利转化为二酮和酮酸酯。可以扩大范围,以77%至86%的产率将三取代的双丙二酸转化为四酮。将该新方法应用于顺式茉莉酮的全合成。
