How could the following synthesis be carried out?

Question

Quizplus · Accepted Answer

The synthesis involves the construction of a functionalized cycloheptane ring. Option A involves several steps, and the use of strong reagents such as MgCl and NaOH, which can lead to side reactions and low yields. Option B involves the addition of a Grignard reagent to a bromo compound, which might not be very selective in the formation of the cycloheptane ring. Option C provides a straightforward approach to the synthesis of the cycloheptane compound, involving the use of a bromo compound, a lithium reagent, and a copper(I) catalyst for the intramolecular coupling reaction. This method is more selective and less prone to side reactions, providing a higher yield of the desired product. Therefore, option C is the best choice.
