Question

How could you prepare the following cyclohexanones by combining a Stork enamine reaction with an intramolecular aldol condensation? (See Problem 23-64.)

Short answer

First we have to find out the starting product by analyzing the given compoundsand find the carbon-carbon double bond which is formed by the dehydration of the initial product formed during the aldol reaction then add carbonyl oxygen after breaking that bond at the relevant carbon atom.
