ETHYL 5- PENTANOATE

Thus 5 nonanone has been prepared from ethyl pentanoate by the sequence O O O... [Pg.893]

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]

An important example of this reaction is the malonic ester synthesis, in which both Z groups are COOEt. The product can be hydrolyzed and decarboxylated (12-38) to give a carboxylic acid. An illustration is the preparation of 2-ethyl-pentanoic acid from malonic ester ... [Pg.549]

If care is not taken in the formation of 1-lithiopropyne, the final product can be contaminated with as much as 1(156 of an impurity, which is presumed to be ethyl pentanoate. This impurity has a GLC retention time on conventional packed columns that is quite similar to that of ethyl (E)-crotonate. The by-product presumably results from the presence of butyl-... [Pg.110]

Experiment 5.152 ETHYL VALERATE (Ethyl pentanoate) h2so4... [Pg.706]

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]
