The reactions include reduction with LiAlH4, sulfonylation with TsCl, deprotonation with sodium ethoxide, and acetylation with acetic anhydride. The goal is to determine the correct structure of product 4 from the given candidates, taking into account the stereochemistry and functional groups introduced during the synthesis."}
