The Claisen and Dieckmann ReactionsUpon exposure of an ester to an alkoxide two things can happen: I. The alkoxide can deprotonate the ester to generate the ester enolate, which, in turn, can undergo addition-elimination to the starting ester.II. The alkoxide can undergo addition to the carbonyl carbon of the starting ester. However, if the alkoxy groups are the same, no net chemical change will result upon elimination.Professor M. J.
