Ethyl pentanoate, Claisen condensation

The sequence begins with a Claisen condensation of ethyl pentanoate to give a p keto ester The ester is hydrolyzed and the resulting p keto acid decarboxylates to yield the desired ketone... [Pg.894]

CH2CH2CH3 Claisen condensation product of ethyl pentanoate... [Pg.1241]

Ethyl benzoate cannot undergo the Claisen condensation, because it has no protons on its a-carbon atom and so cannot form an enolate. Ethyl pentanoate and ethyl phenylacetate can undergo the Claisen condensation. [Pg.576]

Ethyl benzoate cannot undergo the Claisen condensation. Claisen condensation product of ethyl pentanoate ... [Pg.1156]

Another example is the Claisen condensation of two molecules of ethyl pentanoate, leading to ethyl 3-0X0-2-propylheptanoate. [Pg.860]

Give the products of Claisen condensation of (a) ethyl propanoate (b) ethyl 3-methylbutanoate (c) ethyl pentanoate. For each, the base is sodium ethoxide, the solvent ethanol. [Pg.1042]
