【Abstract】 Condensation of methyI β-keto-cyclohexane-carboxylate with diphenyI-bromomethane in boiling benzene gives rise to methyI α-diphenylmethyI- β-keto-cyclohexane-carboxylate. Hydrolysis of the keto ester with 10% alcoholic potash opens the ring to give α-diphenylmethyl-pimelic acid, the thorium salt of which, on pyrolysis at 400-450°, yields α-diphenylmethyl-cyclo-hexanone as expected.更多还原
