2-Methyl cyclohexanone is condensed with dimethyl succinate in the presence of potassium tertiary butoxide giving a solid mixture of isomers of the corresponding alkylidene and alkenyl half-esters. On alkaline hydrolysis this gives β-carboxy-β-(2-methyl cyclohex-1-enyl)propionic acid. The keto-ester obtained by cyclization of the half-ester yielded the corresponding unsaturated ketone after acid hydrolysis
