Question

Show how you would accomplish the following conversions in good yields. You may use any necessary reagents.

Short answer

Reagent used is${\mathrm{Et}}_2\mathrm{NH},\mathrm{acyl}\mathrm{chloride},{\mathrm{H}}_2\mathrm{O}$

Step-by-step solution

Step-by-Step Solution  Step 1: Reagent 

A reagent is a substance added in the reaction to form the product from the reaction, which means they are used to complete the chemical reactions.

Enamine acylation

On the reaction of enamine with base, the formation of enolate occurs, followed by the reaction with acyl chloride formation of the acylated product occur that is di carbonyl product is formed.

Reagent used in the reaction

As ketone reactant is given, which is first converted to the enamine on reacting with the ${\mathrm{Et}}_2\mathrm{NH}$followed by the reaction by reacting with the acyl chloride forming iminium salt as an intermediate which on hydrolysis form the dicarbonyl product which is required

Formation of product

The reaction between carbonyl compound and diethylamine results in the formation of enamine. Finally, the acylation reaction occurs, which leads to the formation of the required product.

The reaction followed as follows:

Enamine acylation
