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
