from methyl ketones, sodamide and diethyl carbonate using these reagents in the molar ratio of 1:3:3 is reported. The yields of β-keto esters approach to those of the preparation using sodium hydride as condensing agent. Furthermore, some cyclopentenolones were prepared from the β-keto esters synthesized by this-procedure.
报道了使用这些试剂以 1:3:3 的摩尔比从甲基酮、钠酰胺和碳酸二乙酯制备 β-酮酯的新方法。β-酮酯的产率接近于使用氢化钠作为缩合剂制备的产率。此外,一些环戊烯醇酮是由通过该程序合成的 β-酮酯制备的。
