Question

Show how the following compound can be synthesized from the given starting material.

Short answer

The answer is,

Reaction mechanism

Step-by-step solution

Explanation

The reaction of acids on alcohol gives an alkene on undergoing dehydration reaction. And the reaction of ketone with strong bases like LDA, Lithium di-isopropyl amine to produce an enolate ion which undergoes reaction to give claisen condensation product.

Explanation

The reaction for the synthesis of the given compound is as shown below.

Reaction Mechanism

The reaction starts with the sulphuric acid reagent. The water molecule is eliminated from the compound giving an alkene.It is the treated with LDA in THF and 2-pentanone giving the product by condensation reaction.
