The electrolysis of ethyl sodiomethylacetoacetate in NN-dimethylacetamide at a platinum anode gives diethyl α, α′-diacetyl-α, α′-dimethylsuccinate, 4, 5-diethoxycarbonyl-3, 4, 5- trimethylcyclopent-2-enone and 4-ethoxycarbonyl-3, 4-dimethylcyclohex-2-enone. Degradation of these products with aqueous ethanolic alkali gives a mixture of dimethylcyclohexenones and trimethylcyclopentenones; the synthesis of 2, 3, 4- ...
