BE Map. The Claisen condensation converts 2 molecules of an ester into a B-keto ester. The reaction starts with the ester in an alkoxide/alcohol solution and is worked up with acid to form the neutral B-keto ester product. Show the curved-arrow mechanism for the Claisen condensation of ethyl ethanoate treated with ethoxide ion. :0: :0: 1. -OCH2CH/CH3CH2OH 2 2. H30* Mechanism Tutorial Step 1a. Classify step Mechanism steps can be classified into a few key processes. Knowing these key processes...
4. Conversion of B into C involves hydrolysis of the ester followed by decarboxylation. On the structures provided below, show the electron flow for the decarboxylation step. CH2Ph 5. The initial product formed on decarboxylation is an enol, which rapidly equilibrates to its keto form under the acidic reaction conditions. Write the complete stepwise mechanism for the acid-catalyzed conversion of the enol into its keto form, Compound C. Ph Ph
The Claisen condensation converts 2 molecules of an ester into a B-keto ester.

2. Consider the following esters. (a) Two of these esters are converted to B-keto esters in good yield on treatment with sodium ethoxide and subsequent acidification of the reaction mixture. Which two? Write the structure of the Claisen condensation product for each one. (2) (b) One ester is capable of being converted to a B-keto ester on treatment with sodium ethoxide, but the amount of B-keto ester that can be isolated after acidification of the reaction mixture is quite small....
