An organolithium reagent derived from trimethylsilyl-4,4-ethylenedioxypentanoate reacts with mixed carboxylic-carbonic anhydrides as a homoenolate anion equivalent. Several monoethylene acetals of 1,4-diketones and the corresponding diketones are synthesized by this way.
衍生自-4,4-亚乙基二氧戊酸三甲基甲硅烷基酯的有机锂试剂与混合的羧酸碳酸酐作为均烯酸酯阴离子当量反应。通过这种方式合成了几种1,4-二酮的单乙缩醛和相应的二酮。
