Abstract
The cyclohexanone derivatives 1-6 containing beta-ketoester and alpha- disubstituted malonic ester moieties in the same molecule were found t o undergo regioselective transesterifications with benzyl alcohol givi ng exclusively beta-keto benzyl esters. On the contrary, the acyclic d erivatives 9, 10 containing beta-ketoester and alpha-monosubstituted m alonic ester groups gave mixtures of transesterified products under th e same reaction conditions.
