Chapter 18, Problem 65P

(a)

Interpretation Introduction

Interpretation:

It should be indicated that how the given compound could be synthesized from cyclohexanone and any other necessary reagents.

Concept introduction:

Reagent is a compound which is added to a system to cause a chemical reaction or test if a reaction occurs.

Cyclohexanone is carbonyl compound which gives variety of reactions including reduction, oxidation and nucleophilic addition reaction depending upon the chemical conditions in the reaction medium.

LDA (Lithium Diisopropylamide) is used as a strong base and it has been widely accepted due to its good solubility in non-polar organic solvent.

Robinson annulation:

In the presence of enough bases, the product of the Michael reaction undergoes a spontaneous intramolecular aldol condensation, usually with dehydration to give a six membered ring-a conjugated cyclohexanone.

Reduction can be done using hydrogen (one of the simplest reducing agent) with a metal catalyst.
