Starting from compound X, which shows specific NMR signals indicating its structure, the problem involves a series of reactions leading to compound W. The key steps include monobromination, elimination to form geometric isomers, and a reaction with a specific diene. The goal is to identify the correct structure of compound W from the given candidates, which is determined to be (1S,4R,5S,6S)-4,5,6-trimethylcyclohex-2-enol."}
