The objective is to determine the correct stereochemical structure of the final product (product 4) from the given candidates. The correct answer is (1R,2S,4R)-4-isopropenyl-2-acetoxy-1-methylcyclohexane, which reflects the stereochemical configuration resulting from the described synthetic pathway."}
