The objective is to identify the correct structure of the final product (product 4) from a list of candidates, considering the stereochemistry and the transformations that occurred throughout the reaction sequence. Understanding the mechanisms and the stereochemical implications of each step is crucial for determining the correct isomer of product 4."}
