A new method for the preparation of various 1,3-dicarbonyl compounds is described. Oxidation of 3-hydroxycarbonyl compounds without substituent at C-2 position by the Corey-Kim reagent (N-chlorosuccinimide-dimethyl sulfide) afforded the stable dimethylsulfonium methylides, which on reductive desulfurization by zinc-acetic acid furnished the 1,3-dicarbonyl derivatives.On the other hand, the same treatment of 2-mono-, or 2,2-disubstituted 3-hydroxy-carbonyl compounds gave directly the corresponding 1,3-dicarbonyl analogous,respectively.
描述了一种制备各种1,3-二酮化合物的新方法。对C-2位置没有取代基的3-羟基酮化合物进行氧化,使用Corey-Kim试剂(N-氯琥珀酰亚胺-二甲基硫化物)得到了稳定的二甲基硫鎓甲基化合物,而这些化合物在锌-醋酸的还原脱硫作用下,生成了1,3-二酮衍生物。另一方面,对2-单取代或2,2-二取代的3-羟基酮化合物进行相同处理,分别直接获得了相应的1,3-二酮类化合物。
