Chapter 21.6, Problem 19P

Interpretation Introduction

Interpretation:

The product of each of the given reaction sequence is to be determined.

Concept introduction:

A molecule that consists of a ketonic group on the $\text{β-}$ carbon atom of an ester is generally known as $\text{β-}$ keto ester. In such structures there is the presence of an active methylene group between the two carbonyl groups of $\text{β-}$ ketoester. Diethyl malonate and ethyl acetoacetate are some examples of $\text{β-}$ keto esters.

These $\text{β-}$ keto esters undergo alkylation. The resulting alkylated $\text{β-}$ keto ester results in the formation of ketone after hydrolysis followed by decarboxylation.
